this is just an activity though

[strange zodiac]

ik but you still have to do it

its something you can use in your future development

[idle dew]

hey guys, not sure if anyone can help but i keep getting an error saying that maximum call stack size exceeded. I think this is a problem with infinite recursion calls, but i'm not sure what im doing wrong. The context of this code is a merge sort, and i created a separate splice function instead of using the splice method, and i think that's where things went wrong. i would appreciate the help, thanks!

[strange zodiac]

Oh

[thin hound]

change let left = mergeSort(splice(arr, 0, mid)); to let left = mergeSort(splice(arr, 0, mid+1));

Also change to newArr[i-start] = arr[i];

Also, to clarify, yes your error is due to infinite recursion, as every time you make a call, you put a call frame on the stack, which takes up space, so if you make infinite calls, you will at some point run out of stack

[flint grail]

why this onclick doesn't work?

This is the javascript

[strange zodiac]

remove the ; on line 12 on your html --> Personitas();

same thing on line 1 ;

indent your code that is inside the function - it would still work but just a pet peeve of mine

[fierce fog]

Thanks so much! This helps a lot

[quiet vault]

hey guys im sorry to bother but can someone pls explain to me what is this error? and how can i make this work? its c sharp

thank you, it did work but honestly i dnt know what a index is i will try to search it up thx but like why does this work if its like this tho?

i dnt get why it works if i put a specific position in the array like 0 in this example but not if i put the i, cause the i is changing and will be i++ so it should give me all the characters no?

im sorry if im asking too much and i know my grammar isnt very good rn cause i dnt know the correct terms in english for programming but like here how could i put it working?

so like this it should work?

oh really? i really should check out the meaning tysm

ohh

thank you!!

i did get it but im gonna take the advice and do it on paper thank you everything works now! ^-^

[red hare]

o index vai de 0 a caract.length - 1

[red hare]

caract é um ponteiro para o início de um bloco de memória

o operador [n] é equivalente a fazeres *(caract + n)

Um array nada mais é que um ponteiro, eu recomendo perceberes primeiro como é que os ponteiros funcionam, vai te ajudar a perceber melhor o problema que estavas a ter @quiet vault

[quiet vault]

Ah não percebi isto

[quiet vault]

Pois vou pesquisar obrigada (sorry im not talking in english guys)

[quiet vault]

Ent no meu exercício ficava caract(caract + i) ?

[red hare]

Não, tens as duas sintaxes possíveis:

caract[i]
// ou
*(caract + i)

São equivalentes

O * está a aceder ao valor no endereço (caract + i)

normalmente a sintaxe com [] é preferida pela sua simplicidade

can anyone help me with react typescript?

this is the object, and the console log's is what i want but the value should be dynamic

but i get this error

i have no idea how to solve it, but i understood the error

[quiet vault]

Ah obrigada!

[quiet vault]

Ah acabei de tentar e não funcionou provavelmente fiz algo de errado

[idle dew]

as i remember, you cant sum the array[] and int in C#, but you can convert char[] into int with ParseInt and sum it

hi guys

does anyone know the difference beetween

I will buy a computer soon for college and Im planning to use it for adobe, programs like stata or R, coding and more 😄

[idle dew]

hi, so this function has two while loops, and in the first loop i declared a 'mid' value, which i then use in the condition for the second while loop. does the value of mid transfer to the second while loop? or are variable only local in the loop that they are declared in?

this is javascript btw

[strange zodiac]

no it doesnt because you only declared the variable mid in the first while loop

so mid is present inside the first while loop block

[idle dew]

okay thank you

[red hare]

Is that C#?

[red hare]

@quiet vault Bem, o C# lida com ponteiros de uma forma muito... estranha
Eu particularmente não aprecio nada, mas isso é outro assunto, em C# eles não gostam de dar esse controlo com ponteiros como tens em C ou C++

Usa mesmo a sintaxe do [] para indexar no array

[quiet vault]

Sim é

[quiet vault]

Pois, eu só percebo um pouco de c# não sei programar nas outras linguagens

[quiet vault]

Ok obrigada!

[fallow sinew]

I'm learning python and I came across a problem that I'm a bit lost on how I approach or solve it. It deals with ASCII art where it has a core and also its 'ring' ``` If I were to input the ring size as 1 and the core size as 0 the result would be:
/
/

and if the ring size was 2 and the core size was 2 it would be
/--
//--\
|| ||
|| ||
\--//
--/ when the ring and core are above 1 it introduces hyphens for the ring and spaces for the core and I'm stuck on how I implement a loop that tackles that... any help or advice would be appreciated ```

[modest delta]

Break the problem down into it's lines since that's what python would do. In the first line what changes between the differen inputs and how would can implement that change. I would give it a shot but can't atm

Hello, sorry for my bad english (im not confident enough)

Can anyone help me to give me an ideas about a new big data technology that could be useful in this pandemic situation?

please

😦

[granite bloom]

In Data Science it is used extensively

[fallow sinew]

    # /--\
    #//--\\
    #||  ||
    #||  ||
    #\\--//
    # \--/
    #This would be the output for the ascii art
    #if the input for core_size and the ring_size was 2
    if ring_Size == 1:
        print('/' * 1 + '\\' * 1)
        print('\n')
    elif ring_Size > 1:
        print('/' * ring_Size + '-' * ring_Size + '\\' * ring_Size)
        print('\n')
    #Core of ASCII
    if core_Size == 1:
        print('|' * 1 + ' ' * 1 + '|' * 1)
        print('\n')
    elif core_Size > 1:
        print(print('|' * core_Size + ' ' * core_Size + '|' * core_Size))
        print('\n')
    #Bottom portion
    if ring_Size == 1:
        print('\\' * 1 + '/' * 1)
        print('\n')
    elif ring_Size > 1:
        print('\\' * ring_Size + '-' * ring_Size + '/' * ring_Size)
        print('\n')

    

def main():

    while True:
        ring_Size = int(input('Rings: '))
        core_Size = int(input('Cores: '))
        if ring_Size == 0 and core_Size == 0:
            break
        ascii()

This is what I tried to do, it executes but doesn't even go thru main. I'm still learning python, not sure what I can do so that the main() executes and at least goes thru the while loop so I can debug

anyone know what might solve this problem?

[modest delta]

You call the function without inputs

ASCII() should have two inputs ring and core size

Pass in the variables

[fallow sinew]

I passed them in to ascii within main "ascii(ring_Size, core_Size)" it executes but still doesn't ask for the user input

I know it'll have accessed the while loop if it asks for the inputs but it hasn't

[modest delta]

Ohh

Try getting rid of the whole loop

Or just hard code the values and pass them in

[fallow sinew]

figured it out I needed ```if name == "main":
main()

[crisp robin]

[orchid pier]

how would i code to solve the polynomial by just using addition and subtraction

would the exponents require me to have a nested for loop?

[ionic arch]

@orchid pier Hi!, if you are using python there is a exponential method that you can use to perform exponent operations, so you don't need a loop for doing an exponent. What language are you using may I ask?

[orchid pier]

java

[compact whale]

solving a fourth degree polynomial is quite difficult and has a very complex formula. by solve did you mean finding the value of y for a given value of x?

@orchid pier

[orchid pier]

yes

so you would be given x to be the value of 2 lets say

and you solve for y

its just im not too sure how to solve for the powers using addition only

[compact whale]

yes I think nested loops is the way to go

[orchid pier]

do you know how about i would go making this nested loop?

im having a hard time visualizing being able to code to calculate something 3^4

[compact whale]

well for inner loop you can add x for x number of times and in the outer loop fix the index of the exponent

and for this you can use recursion

[orchid pier]

Just ask

[wispy hamlet]

    return 3*pow(x, 4) + 2*pow(x, 3) - 6*pow(x,2) + 8*x -2;
}```

Is that what you wanted ?

The pow(x, y) function returns the value of x^y

I think it's Math.pow or sth like that instead of just 'pow', but I let you look it up

Btw, finding the value of a polynomial at a certain x is not called "solving" the polynomial

[idle dew]

you can use ** instead to clean code

[wispy hamlet]

not in java

If I recall correctly

[idle dew]

now i remember why i dont want to study java

[solemn mesa]

hahahahha

[red hare]

I really dislike Java

So is JavaScript, doesn't make it a good language... just practical i guess

Agree to disagree

Java the way it works internally is very restrictive and... ugly honestly

Plus it gives away efficiency open handed

I would

Java is good if you wanna code something quickly

Besides that... it sucks

For starters, for a OOP language, not allowing operator overloads is just ridiculous

Also, no real way of saying if a object is destroyed or not, rather "leave it to this entity, let's call it garbage collector, and eventually it will clean out the memory"

PAHAHAHAHA

Dude, that's what java is for

it's meant for OOP

wtf

are you saying

Who said anything about classes as in school?

In that it sucks

that's it

I did, a few of them

If you ignore what i type its not really my problem

What

You asked "How so", I named a few things, and then you say that

I used the language

That's as much experience you need to give your opinion about something

Dude scroll up

also, the geniuses that made Java didn't even make static initialisation thread safe

Like, bruh

I will, cause that's dumb, I should be able to control when and how my object dies

And matlab

I do

[gray urchin]

hey does anyone here know how to return the time of an insertionsort algorithm in code?

[verbal wraith]

Depends on what language you're using but every language has a library for time related functions

You can use the structs and functions in the 'time' library to measure the time between the start and end of a function

Programming on Windows is such a nightmare

Is that java? Java uses unicode chars by default iirc

Unicode just means that It can represent more characters than ASCII

It also takes twice as much memory space tho, since unicode needs a type bigger than 1 byte (2 bytes)

Why is the time complexity of Quicksort (eg using Lomuto) when the input list is a list of equal values (eg [0, 0, 0, 0, 0, 0]): O(n^2) and not O(n) ?

[solemn mesa]

Wikipedia mentions it here - https://en.wikipedia.org/wiki/Quicksort#Worst-case_analysis

"This may occur if the pivot happens to be the smallest or largest element in the list, or in some implementations (e.g., the Lomuto partition scheme as described above) when all the elements are equal."

Hey everyone, I am struggling a bit on coding stuff (learning c++ btw). I flunked last semester and I've decided to improve myself to be better. The resources given by my uni is not bad but I can't seem to relate with the examples they give from their pdf slides. Can anyone recommend any websites that is friendlier towards those who starts c++ from zero? (I'm learning more on Object Oriented Programming this semester but most of the examples are given in code and I find it hard to understand since my basics in c++ is considered as lower than average, I have the passion to learn but somehow it's hard to find resources other than my uni's pdf slides.)

[cerulean patrol]

Good morning I want to ask a question about Java
When you create a variable:
float pi = 3.14F;
What does the F represent at the end?

[subtle parcel]

Good morning! By adding the F, you're fixing the decimal part of the number instead of any small difference in the decimal part. You can check this using the conditional operator whether 3.14 is actually stored as 3.14 or not with and without the f

It explicitly indicates the compiler that the number is a floating point number instead of a double

[cerulean patrol]

But still it makes no sense decimal is a way to convert the meaning of a value not to change the value. I don't get the meaning of using the word "decimal" here, I mean 3.14 is a decimal number.

[granite sleet]

besides the grammer and spelling can someone look at my gaming profile website it was kinda rushed but https://whoskorus.netlify.app/

[thin hound]

As I understand it
3.14 as an immediate, is of the datatype double. This means that the variable float pi can't hold it, because it will only hold a float. In order to actually get a float variable to hold your double number, is to convert it to a float, by using the suffix F

[thin hound]

I wonder if it has something to do with your while-loop. Try to use the form

void loop(){
  Serial.println(msg);
  if(serial.available() > 0){
    // Actually do something here
  }
}

I haven't programmed for arduino, so I'm not sure if the while-loop actually is the issue, but might be worth a shot

[knotty pond]

its cool, but why are the games blurred, also linking the equipment, or linking the discord could be cool, i think, rest is clean

[granite sleet]

thank you i plan on adding the game photos soon, didnt think of linking the equipment and the discord ill do that iswell

[subtle parcel]

Okay. All numbers containing the point "." are assumed to of the type double. So while the format of using this statement is syntactically correct the semantics is not. This will lead to conversion of a double literal into float literal which leads to loss of precision. Using of F avoids this conversion by explicitly stating this is a floating point literal.

[cerulean patrol]

Now that's what I am talking about !! Thank you so much God bless you

[subtle parcel]

You're most welcome :))

JOSEPHUS FLAVIUS Task
One of the talents that Josephus Flavius possessed was the mathematical skill, which according to legend saved his life. When the Romans trapped 40 of Flavius's followers and him, they made a death pact in which the Romans would not get them, they rather be dead. They took deadly counts in a circle of soldiers. Each third was killed. The count continued until one man was left. It was man who took 31st place in that circle. Yes, It was Flavius. He had another opinion about life, death and his special assignment in this war. Below you see the tool, which can calculate for you any amount of numbers for any picked out number and for any number left (less than total, of course). Just remember, Flavius quickly solved such a problem in his head without any computer program. Hopefully you will never be at needs to use this tool for saving your life but maybe you'll find another reason to use it.

Task: find the location(index) of the single person who remained alive.

the output for the first call should be '4␣x␣1␣=␣4\n4␣x␣2␣=␣8\n4␣x␣3␣=␣12\n4␣x␣4␣=␣16\n4␣x␣5␣=␣20\n' and for the second call it should be '3␣x␣1␣=␣3\n3␣x␣2␣=␣6\n3␣x␣3␣=␣9\n3␣x␣4␣=␣12\n3␣x␣5␣=␣15\n3␣x␣6␣=␣18\n3␣x␣7␣=␣21\n3␣x␣8␣=␣24\n3␣x␣9␣=␣27\n3␣x␣10␣=␣30\n'

but now when i call it the second time its '4␣x␣1␣=␣4\n4␣x␣2␣=␣8\n4␣x␣3␣=␣12\n4␣x␣4␣=␣16\n4␣x␣5␣=␣20\n3␣x␣1␣=␣3\n3␣x␣2␣=␣6\n3␣x␣3␣=␣9\n3␣x␣4␣=␣12\n3␣x␣5␣=␣15\n3␣x␣6␣=␣18\n3␣x␣7␣=␣21\n3␣x␣8␣=␣24\n3␣x␣9␣=␣27\n3␣x␣10␣=␣30\n'

[edgy crater]

how about the global variable final? you added your previous result in final and it was not cleared when you call table() second time, so its result is all gathered

clear the value of final before calling table(3,10)

hey guys is someone here that has proteus 7 installed and can open a file for me?

[idle dew]

does anyone know why it doenst add 3 to the string? ```def count(a, b):
print()
if a >= b:
return ''
else:
partial = count(a+1, b-1)
return str(a) + partial + str(b)

a = 0
b = 6
s = count(a, b)
print() ```

When i get rid of the equal sign it gives me an error

[idle dew]

nvm

[grizzled stirrup]

Hallo i have a problem.

[edgy crater]

because of return ''

when a and b become 3, it returns nothing

[edgy crater]

and i dont know what error was occurred, because you didnt attach the error message,
but it seems that it has an ambiguous condition to finish its recursion.
we know your intention was 0123456 but your computer doesnt know that.. it keeps calculating a=4, a=5...so on and returning ''. MAYBE this is the reason of your error

[cerulean patrol]

Hey Bois I am a bit confused with Java, what exactly is a class and a constructor?

[tepid grove]

a class is just a way of organizing methods/variables in their own instance, and a constructor is a way you can specify the creation of a class

like

class C {
  int x;
}

has its own variable called x

and you could specify the value of x if you add a constructor:

class C {
  int x;
  public C(int y) {
    x = y;
  }
}

so if I were to make 2 instances of C

C first = new C(5);
C second = new C(6);

first.x = 5
second.x = 6

so, "first" and "second" are defined as the same type of thing (the same class), but they can have different values for their variables

[open solstice]

with constructor you create an object of that class

you can create many of them

If you know lists think about them

ArrayList<String> list = new ArrayList<>;

basically you create an arraylist object

[solemn mesa]

hey ace! i am a current undergrad studying computer science. depending on how much you know already (have you ever written code vs. what kind of tech interests you), one thing is probably chase what you are interested in within the computer science field. I knew nothing about the field a year ago, but now I've evaluated what I love to do personally and I was able to direct that towards topics such as software engineer as well as data retention concentration within the computer science "umbrella". Thinking that through has really helped me in my journey for a degree and a career afterwords. As for growth/salary etc I don't know too much about that.

The same thing happens with char arrays. When you write cout<<charArray; what you have stored in the string is written and not the memory address of the first element of the array as it happens with integer type arrays

#include <iostream>
using namespace std;
int main(){
    char name[20] = "Albert Einstein";
    cout<<name<<endl; //Console shows Albert Einstein
    int _array[20] = {1,2,3,4,5,6,7,8,9,10,11,12,13,14,15,16,17,18,19,20};
    cout<<_array<<endl;   //Console shows the memory address owned by the first element of the array.
    cout<<*_array<<endl;  //Console shows the data stored in the memory address of the first element. Writes 1.
    return 0;
}

Hope this can help you!

count = 1 #my counter and its first value
sum = 0 #accumulator and its first value

while count <= 10:
    sum = sum + count
    count = count + 1 #increment the count by one
print(str(sum) + " is the sum of one to ten.")

how do i make it so that it prints the sum after each number?

HELP

[wheat silo]

Try to put print below the sum variable. It will be like:

count = 1 #my counter and its first value
sum = 0 #accumulator and its first value

while count <= 10:
    sum = sum + count
    print(str(sum) + " is the sum of one to ten.")
    count = count + 1 #increment the count by one

The output will look like:

1 is the sum of one to ten.
3 is the sum of one to ten.
6 is the sum of one to ten.
10 is the sum of one to ten.
15 is the sum of one to ten.
21 is the sum of one to ten.
28 is the sum of one to ten.
36 is the sum of one to ten.
45 is the sum of one to ten.
55 is the sum of one to ten.

If that's what you're looking for

[idle dew]

Oh i already solved it but thanks
same output

# A series of marks is to be entered and averaged.
# Before you enter the series you are to have the
# program ask you how many marks there are in the series then

im having trouble doing this oneee

i can do it with for loop but not while

@wheat silo (sorry for pinging you)

[wheat silo]

[wheat silo]

Ah, my apology, give me 3 mins

[idle dew]

its all good

[wheat silo]

Can you elaborate on which part the while you want to use in this case?

[idle dew]

wdym?

[wheat silo]

While will be use to count the length or to average? it sounds like it has 2 problems: size of the series and find the average

[idle dew]

for lenght (i think)

but the output might look something like this

thats for my for loop

[idle dew]

u there?

[wheat silo]

Ah, this is how you want it to looks like, I was thinking it looks like a list as series [95, 99, 80] as input

[idle dew]

oh not list

[wheat silo]

So you have done it this way, you basically already solved it, just change for loop into while use the number of marks

n_mark = int(input("input number of the marks:"))

sum = 0
count = 1

while count <= n_mark:
      input_mark = int(input("Please enter mark number: "))
      sum += input_mark
      count += 1

avg_mark = sum / n_mark
print(str(avg_mark)) 

[idle dew]

i kinda dont get the sum part

but thanks

[wheat silo]

sum is just add each mark, since the while doing the loop until it satisfied by the n_mark
let's say we fiil n_mark by 2, then we add 11, sum = 11
then back to the top again, we add 11, sum = current sum + sum just added, sum = 22

sum += input_mark is another way of writing sum = sum + input_mark

[idle dew]

some help here.....there's a bug in my code....

[strange zodiac]

can you give more detail than that....

[idle dew]

it's not printing anything

[wheat silo]

def fractional_part(numerator, denominator):
    number = 0

    if type(numerator) is int and denominator != 0:
        number = (numerator/denominator)-(numerator/denominator)

    else: print("Seems like numerator isn't int and denominator is zero.")

    return number

is , a keyword in python to check the object is the same or not.
Also, in python we don't have to define the type of the variable all the time unless we need it to do it in explicit way.

i have one more question

# Ask the user for an integer at which to start counting.
# Ask the user for an integer at which to stop counting.
# Count from start up to stop by 1s. Also try to make it count by 2.

startValue = int(input("Enter the starting number: "))
stopValue = int(input("Enter the stopping number: "))

while startValue <= stopValue:
     print(startValue)
     start = startValue + 1

how do i make it count by 2s

in the print statement
i know in for loop you could just

for i in range(1,10,2):
    print(i)

@strange zodiac

[strange zodiac]

i believe you can just ask for another input of how much it could count by

so you can just replace that line in your while loop start = startValue + countBy

[idle dew]

oh not in the print statement?

[strange zodiac]

wdym in the print statement?

[idle dew]

the one where it says print

i thought itd be like
print(startValue,(stepValue))

[strange zodiac]

i dont think so

cause that print statement is there to print out the values at which it is counting by

so it displays the numbers startValue = 1 stopValue = 5 it will display

1
2
3
4
5

[idle dew]

alright i get it thanks

[strange zodiac]

yeah if you want you can make it so that if the user doesnt input a value for the countValue make it default to 1

Anyone good at coding kindly ping me : )

[idle dew]

Ask for a student’s name. Then repeatedly ask the user for a mark,

and it calculates the sum at the same time. You can print

out the current sum as you go to test if the sum is working

properly. If the mark entered is less than or equal to negative 2, or

greater than 100, then it will say “invalid input” and it is NOT added to the

sum. When the input is -1, it finishes asking for the marks and outputs the

student’s name plus how many valid marks were entered and the sum.

name = str(input("Please provide your name: "))
sum = 0

while True:
    mark = int(input("Enter the mark: "))
    sum += mark
    if mark <= -2 or mark > 100:
        print("invalid input")
        continue

Always stop running the application before your rebuild

You can't. There is always something in the array. In some cases it will be junk data, in other cases it will be initialized to 0 (or respective 0-value for data type), depending on scope.

i think you missunderstood between [ ] and []. space letter is a string, it don't present any kind of empty or null value. If you want to check an array is empty, use includes(arr) when arr = []

i tried to solve this, my code is working same input and output but when i submit it's saying wrong. can anyone tell me what i did mistake?

here is the code

#include <stdio.h>
int main() {
    int a, b, c;
    scanf("%d %d %d", &a, &b, &c);
    if (a >= 1 && a <= 9 && b >= 1 && b <= 9 && c >= 1 && c <= 9 )
    {
        if (a == b)
        {
            if (b != c)
            {
                printf("Yes\n");
                return 0;
            }
        }
        else {
            if (a == c)
            {
                printf("Yes\n");
                return 0;
            }
        }
    }
    printf("No\n");
    return 0;

}

what is a,b,c. As i understand it a,b,c, is 0 atm

[calm magnet]

@idle dew I think you are missing the case where b and c are the same

Heyy guys I need some help in coding for OOP for C or C++

How do I write a program for the solution of heat or wave equations. Using at least one object oriented programming concept.

[idle dew]

Thinkpads are probably your best bet, what kind of work?

[trail schooner]

Is anyone able to help me with some programming? Or could anyone direct me to some programming discords where I would be able to ask for help? I currently need help with Java data structures

[wide hound]

anyone here familiar with LOGO

or anything similar

is there a way to add temp sensory onto this?

jus computer engineering coursework and some youtube videos and stuff

i wanna run arch

[lucid tartan]

Hello can someone help me to do a working summary? i don't even know how to start (in html/css/java)

(ping me pls)

[lucid vector]

`You will be given a list of tuples where each tuple indicates a point i.e. (x, y) in a 2-dimensional coordinate system. You need to write a python program to find the minimum distance and the point that is

closest to the origin i.e. (0,0)
Hint: The formula of distance = √((Δx)2+(Δy)2 )

As you are calculating the distance from the origin (0,0), you can simply use distance = √(x2+y2 )

You can create a list of distances from each point and sort that list using your personal

favorite sorting algorithm.
Sample Input 1 points = [(5,3), (2,9), (-2,7), (-3,-4), (0,6), (7,-2)] Sample Output 1 Minimum distance = 5.0

Here the closest point is (-3,-4) which has a distance of 5.0 from the origin.
Sample Input 1 points = [(1,7), (4,5), (-1,7), (-2,0), (1,1), (5,-1)] Sample Output 1 Minimum distance = 1.4142135623730951 Here the closest point is (1,1) which has a distance of 1.4142135623730951 from the origin.`

[lucid vector]

Can anyone help me with this problem? I have to use selection sort or bubble sort to solve this problem. I tried to use sort in nested list but was generally error

`points = [(5,3), (2,9), (-2,7), (-3,-4), (0,6), (7,-2)]
list1 = []
for i in points:
sum = (i[0]**2+i[1]**2)**0.5
list1.append(sum)
for i in range(0,len(list1)-1):
for j in range(len(list1)-i-1):
if list1[j] > list1[j+1]:
temp = list1[j]
list1[j] = list1[j+1]
list1[j+1] = temp
print(list1)

print("Here the closest point is ""which has a distance of",list1[0],"from the origin.")`

This is the code I wrote but couldn't able to print the tuple

[idle dew]

What was the error?

[lucid vector]

Tried to use selection sort in nested list got error int type not subscrible tried to fix it but couldn't able to do it

[lucid vector]

I solved it without using sort but want to solve it with selection or bubble sort

[idle dew]

This code worked for me:

>>> [5.0, 5.830951894845301, 6.0, 7.280109889280518, 7.280109889280518, 9.219544457292887]

[lucid vector]

Yes it works but I have to print the tuple

Output 1 Minimum distance = 1.4142135623730951 Here the closest point is (1,1) which has a distance of 1.4142135623730951 from the origin.

[idle dew]

I see, in that case you could use a dictionary, or alternatively also modify the points list in respect to to the sorted one

That would be 2 swap operations in the bubblesort

[lucid vector]

Tried to do both but unfortunately not worked the code i wrote

Thanks! I will try it again

[idle dew]

No problem

[lucid vector]

How would you do if you use dictionary?
Key:value sort ?

[idle dew]

(1,1) -> 1.41421..

Key is the point a value is the distance

[lucid vector]

Okayy

[wide hound]

on a serious note, try to think of a related problem that you solved before and use that knowledge

[lucid vector]

I'm kinda beginner so that's why struggling 😅 I created the dictionary key is the points and value is the distance couldn't able to use selection or bubble to sort the dict

If there is anything with web-developing, html/css/js/reacr.js, I will help ❤️

[mental lark]

How do you actually learn your cs classes, algorithms or programming in general? I feel its like only memorising lines of code by heart and isn't really intuitive most of the time

[terse crow]

Just try writing it by yourself in any online compiler and try to be persistent and focus. Try to understand the code if you are unable to make one yourself and then code it.
Trust me, this helped me try codes myself and the feeling that you get after getting that right output when you write the code yourself... damn man

It takes time but hope you will get there soon.

All the best !

[ashen helm]

is there any free coding online classes for begginers?

[mental lark]

Yeah thats what I've been experimenting with. Thanks though !

Does anyone know a tool for converting HTML to XHTML 1.0 Strict?

[wild hound]

There are some general style points that I would make:

With the use of an additional string for holding processed input, you could use a range-based for-loop to process the input. Also, there are inbuilt functions that will handle a lot of the processing you want, e.g., isalpha(character) is a lot cleaner and clearer than (x[i]<'A' || x[i]>'Z') && (x[i]<'a' || x[i]>'z'). Replacement of K's with C's can be done with the conditional operator.

string temp_input_string{};
string input_string{};

cout << "inserire il messaggio" << endl;
getline(cin, temp_input_string);

for (auto character : temp_input_string) {
  if (isalpha(character)) {
    character = toupper(character);
    input_string += character != 'K' ? character : 'C';
  }
}

This is C++, not C, so use a vector unless you have a good reason not to. You can replace your 5x5 C style array with a 5 element vector of strings. Also, replace the magic numbers with what you actually mean 'A' and 'K' (or 'a' and 'k') not 65 and 75 (or 97 and 107), this is quite an important point since your mistake would have been easier to spot if you wrote it this way. A good rule of thumb here is "say what you mean".

vector<string> mat(5, string(5, ' '));  
char c = 'A';
  for (auto& row : mat) {
    for (auto& character : row) {
      character = c;
      c++;
      if (c == 'K') {
      c++;
    }
  }
}

I'm not sure if I got the last part right, because, I'm not entirely sure what this was supposed to be doing. However, the redefinition of mat above allows use range-based for-loops again, and using strings in mat allows us to use the find function from <algorithm> to find the index of any place in the row that matches the current character in the input string.

string dot_string{};

for (auto input_character : input_string) {
  for (auto row : mat) {
    int idx = row.find(input_character);

    if (idx != string::npos) {
      dot_string += string(idx, '.') + ' ' + string(idx, '.');
    }

  }
}

a friend of mine has been facing this error in the server since yesterday, he had left the server a day ago but on joining again, he isnt able to access the general chat room, I did tell him to do a lot of stuff but none of it seems to work
does anyone here have any clue? thank you in advance.

[sharp breach]

these are the only available rooms in the server for him.

[wispy hamlet]

1. Check all the "mute" roles, waiting a few seconds between each check, then uncheck them all.
2. Leave the server and get invited again

Those seem like basic steps, but last time I answered a question like that, the dude hadn't tried those 🤦‍♂️

Hey guys,
I'm trying to write a program in C, but I just can't figure out how to use pointers in order for everything to work properly. The program is supposed to be a snake game, but I can't even run it sadly. I've been stuck on this problem for a long time now if anybody could help me some way it would be greatly appreciated. Please note that the program is incomplete, that's why some parts seem unnecessary.

[worldly kestrel]

does anyone know how cplex works in java? Need help

[wild hound]

I've found a couple of issues with your code:

In the function moveLeft you are calling the positionSnake function as:

positionSnake(snake.bodyX[i] - 1, snake.bodyY[i], slots); 

This should be:

positionSnake(snakeptr->bodyX[i] - 1, snakeptr->bodyY[i], slots)

In the positionSnakeHead and positionSnake functions your input to the functions is char* slots however in the function you call this as slots[x][y]. If you send the 2D array slots to this function as char* then the function does not know the size or shape of the array, thus slots[x][y] means nothing to it. You can either modify the function to take a 2D array or keep the char* by indexing it as you do in printGame.

Throughout the move functions you use: snakeptr->bodyX[SIZE] and snakeptr->bodyY[SIZE] repeatedly. SIZE is defined as 2, and you appear to be using this to access the last element in each array. But 2 is the size of the arrays bodyX and bodyY, the last element has the index of 1. Because indexing in C starts from zero, the last element is always N-1, where N is the size of the array.

You should replace every instance of snakeptr->bodyX[SIZE] with snakeptr->bodyX[SIZE-1], and every instance of snakeptr->bodyY[SIZE] with snakeptr->bodyY[SIZE-1].

After all of the changes made above the code compiles for me.

hi, I've just made a program to count the number of prime numbers in a given sequence of integers. it's written in c++, and I'd really appreciate it if someone could help me check whether it's okay. thx a lot, happy studying guys
here's code: (N is for the number of inputted integers, c is for the total count at the end, d is the number of divisors of a given number in the array)
#include <bits/stdc++.h>

using namespace std;
int N, n, i, c=0, d;
long long a[100000];

int main()
{
cin >> N;
for (i = 0; i < N; i++)
{
cin >> a[i];
d = 0;
for (n = 2; n <= a[i]; n++)
{
if (a[i] % n == 0)
d++;
}
if (d == 1)
c++;
}
cout << c;
}

[craggy sierra]

the logic for your code is fine, but you don't need to count the number of divisors

once the condition if a[i] % n == 0 you already know it isn't a prime number

so you just can do c++ immediately and move on

the variable d doesn't do anything given what you want to do

[unborn wagon]

didnt start learning C++ yet and it already hurts my brain lol

[wild hound]

You don't need to check all the way to a[i], if you haven't found any factors less than or equal to sqrt(a[i]) then there won't be any factors greater than sqrt(a[i]). Also, you can check for divisibility by 2 separately, if a[i] is divisible by two then it is not prime. If a[i] is not divisible by 2 then it won't be divisible by any even number, so you don't have to check for divisibility by any other even numbers.

[wild hound]

I’m a bit rusty so don’t take this as gospel truth, but here is how I would approach solving this problem. First, substitute the given C and k into the definition of what it means for f to be O(g).

|x^2 -8x + 26| <= C|x^2|, for all natural numbers x > k.

As an example, for question 2(e) part i., with C = 1 and k = 4, this gives:

|x^2 -8x + 26| <= |x^2|, for all natural numbers x > 4.

For this equality to hold, -8x+26 would need to be:

• less than or equal to 0 (to make f(x) less than or equal to x^2), but also
• greater than or equal to -2x^2 (so that you don’t end up with negative values so large that their absolute value is greater than x^2).

You can split this into two cases that you prove separately:

-2x^2 <= -8x+26, and
-8x + 26 <= 0

You must show that both of these inequalities hold as long as x > k, which for this question means natural numbers x > 4.

When I worked through this, I found that the first holds for all real values of x. The second holds for values of x greater than or equal to 3.25. Both of these sets of values include all natural numbers greater than 4, which would mean that this one is true.

[glad siren]

thx for the suggestion. i have tried that but then i realised that what i want to count is prime numbers, not non-prime numbers which can be counted using if a[i] % n == 0 XD can i do something like c = N - c at the end instead?

[glad siren]

my teacher also guided me to do it like this. yet i couldnt understand it so i just tried making a code by the very definition of prime numbers which can only be divided by 1 and itself lol

[wild hound]

You could also consider moving your primality test into a separate function that takes the number you want to check and returns true if it is prime and false otherwise. Then, in your main function, the prime counting would reduce to:

if (is_prime(a[i])) {
  c++;
}

You could then have conditional returns from this function that return false when a factor is found that is not equal to the number itself. And, from a software development standpoint, having the implementation of the primality test in its own function would make it easier to optimise and reuse.

Hi everyone, I'm trying to make a Pokedex in C++ as an assignment, but I can't figure out how to read pokemon data from a .txt file, create objects of a "pokemon" class and then save them to a vector.

My .txt file looks like this:
1 Bulbasaur 6.9 0.7 1 Both Grass Poison;
2 Ivysaur 13.0 1.0 2 Both Grass Poison;
etc.,

basically constructor looks like (number, name, weight, height, numberOfEvolution, gender, type and secondaryType). I would like to know how to create objects using this data in my main() function (it's empty as of now cuz all my ideas didn't work). I'll really appreciate some help <3

[wild hound]

Could you post an example of your Pokemon class, and something you tried that didn't work, so that we have something more to work from?

[coarse wagon]

struct pokemon
{
int number;
float weight;
float height;
int evolutionNumber;
std::string name;
std::string gender;
std::string type;
std::string type2;

pokemon (int Number, std::string Name, float Weight, float Height, int EvolutionNumber, std::string Gender, std::string Type, std::string Type2);

};

This is my Pokémon structure

int countPokemon(std::string fileName = "/Users/kuba/Desktop/Projekt/Projekt/Database.txt")
{
int pokemonNumber = 0;
std::string line;
std::ifstream read(fileName);

while(std::getline(read, line))
    pokemonNumber++;

std::cout<<"Number of Pokemons: "<<pokemonNumber;
return pokemonNumber;

}

And this is my other function that counts how many Pokémon are there

My main() is completely empty

One of the things I tried is something like this (test version that didn’t work):

std::ifstream test("/Users/kuba/Desktop/Projekt/Projekt/Database.txt");

std::string name, gender, type, type2, number, evoNumber, height, weight;
int number1, evoNumber1;
float weight1, height1;


for (int i = 0; i < 7; i++)
    {
    getline(test, number, ' ');
    
    
        
    getline(test, name, ' ');
    getline(test, weight, ' ');
    getline(test, height, ' ');
    getline(test, evoNumber, ' ');
    number1 = stoi(number);
    evoNumber1 = std::stoi(evoNumber);
    height1 = std::stof(height);
    weight1 = std::stof(weight);
    
    getline(test, gender, ' ');
    getline(test, type, ' ');
    getline(test, type2, ' ');
        
    pokemon test (number1, name, weight1, height1, evoNumber1, gender, type, type2);
    }

[wild hound]

Do you also have the implementation of the pokemon constructor?

[coarse wagon]

I have this in my pokemon.cppfile:

pokemon::pokemon(int Number, std::string Name, float Weight, float Height, int EvolutionNumber, std::string Gender, std::string Type, std::string Type2)
{
number = Number;
weight = Weight;
height = Height;
evolutionNumber = EvolutionNumber;
name = Name;
gender = Gender;
type = Type;
type2 = Type2;
}

[cerulean patrol]

@everyone Fellow programmers do you have any forums for the Minimax thingy, I kind of need to make an AI.

[wild hound]

First, change the names of the ifstream and the pokemon objects that you are creating, these shouldn’t have the same name and there are much better names than “test” for both of these objects.

Second, make sure that your file is actually being read. If your ifstream is called file_in, then this can be done by calling: file_in.is_open() if this comes back as false then the program cannot find the file.

Third, check the line: getline(file_in, type2, ' '); You will notice that type2 becomes something like “Poison;\n2”. This getline is reading all of the way to the next space, which it is finding in the line for the Ivysaur, after the pokemon number. This is the reason for the 2 at the end of “Poison;\n2”. The next time the loop runs it will read up the next space, which means that “Ivysaur” is loaded into the string number. The program then crashes when you try to convert the string “Ivysaur” to an integer with number1 = stoi(number);

A quick and dirty fix for this problem is to change the last getline to:

getline(file_in, type2, ';');

This will read up to the semicolon that you have at the end of each line, and then you can use:
getline(file_in, some_other_string_variable)
This will bring you on to the next line, ready to read the next pokemon.

[coarse wagon]

Thanks, I managed to make it work as intended!

[wild hound]

You could try the maths thread for this, but I don't think e^x would work in the first case. e^x is one to one for R to R, but not from R to Z, as there are a lot of real numbers x that f(x) = e^x wouldn't map into the integers. I think that the answer for the first one would be that no such function exists, since every distinct element must be mapped to a distinct element, but I don't think this can be done since Z is countable but R is uncountable.

For the second part, f(x) = x works (I think) as every distinct x in Z gets a distinct f(x) in R (so it is one-to-one) but not every element in R has an associated x in Z (so it is not onto). Also, e^x would work too in this case, in fact, probably a lot of functions would work if my reasoning is sound.

Hello everyone, I am trying to predict which products are more successful in comparison to another, and how much should be ordered per season. I have no idea where to start as I only have information of the end stock per week. Is it a good idea to make an new column 'sales' by subtracting the end stock of each following week?

[open solstice]

if number of sales makes a product successful yes that's a good idea

and then you can combine weeks into seasons

Anyone who can help me in editing videos

[wild hound]

The way to do this is using fsolve which is described in the Matlab documentation here: https://www.mathworks.com/help/optim/ug/fsolve.html. Basically you create a function that contains your system of equations which you write in the form F(x) = 0. For example:

function F = equations(x)

P_MH = 3.43e-4;
P_MM = 5.55e-5;
P_F = 500;
P_R = 500;
P_P = 20;
A_M = 3595;
n_F=550;
n_HF = 495;
n_MF = 55;

% Equation (1)
% n_HF = n_HR + n_HP
% 0 = n_HR + n_HP - n_HF
F(1) = x(1) + x(2) - n_HF;

% Equation (2)
% n_MF = n_MR + n_MP
% 0 = n_MR + n_MP - n_MF
F(2) = x(3) + x(4) - n_MF;

% Equation (3) - Dalton’s Law of Partial Pressures 
% P_F = p_HF + p_MF
% 0 = p_HF + p_MF - P_F
F(3) = x(5) + x(6) - P_F;

where the vector x contains the unknowns you are trying to solve for.

You then solve for this by creating a function handle to your function:

fun_handle = @equations;

and then run it using fsolve(fun_handle, x0) where x0 is a vector containing initial values for your unknowns.

Unfortunately, when I run this it tells me that there is no solution, which I think means there is either a problem with the way I have typed in all of the equations or the equations you provided contained an error. Either way you should try this method for yourself and see if you get a better result.

[raw knoll]

thank you so much! i'll try it now

[raw knoll]

There is indeed an error in the solution. I still haven't got the solution though.

how hard/easy do the mathematics problems have to be?

[blissful gazelle]

elementary kinda math

addition sub and at max multiplying and dividing

since its c++ use sfml for ui

[blissful gazelle]

thought about that but our professor just had to make things harder by mentioning that it has to be a GAME not a just a quiz of some sort

[blissful gazelle]

and mind explaining that a bit more/

?*

[mossy hemlock]

If she allows it you can put your logic in unreal engine, it uses c++ either way

[blissful gazelle]

but isn't unreal a bit complex to learn in 2 weeks? is it possible? cuz if so then hell yeah

[mossy hemlock]

Yeah idk about that haha really has to do with how much work you can put in

Also really what does the teacher want out of the project

If she wants to see you writing complex logic then you shouldnt think of things such as using unreal

Given ofc that you have 2-3 weeks

If she’s looking to see an actual working game given that it was coded with c++ then definitely unreal is a good idea

You get me?

[blissful gazelle]

well yeah that's probably what's going on through her devilish brain

but anyways

if it's possible within 2 weeks(no matter how much time it takes) then i shall take it as a challenge upon mysekf

myself*

Thank ya'll for the help ❤️

[mossy hemlock]

I think if you take a day or two to plan what to do not only is it the right way to go about it but it’s required

So if after a couple of hours of research you realize it’s not realistic to go with unreal it’s completely okay

Hey guys, I'm trying to write a function which takes command line arguments(argv,argc) and an array allocated on heap memory as parameter, and it should check if there is a number entered as command line argument and if yes, it assigns it to N as a value, otherwise it asks for a number from the user. Then it should proceed to fill the array with numbers which I did with a for loop. My problem is that it just doesn't seem to work, pointers are the main problem I think. Any help would be appreciated!

    int N = 0;
    int *array = (int *) malloc(N * sizeof(int));
    Scan(argv,argc,&array,N);```

```void Scan(char *argv[], int argc, int **array, int N){
    if(argc != 2){
        printf("Enter a number!\n");
        scanf("%d",&N);
    } else{
     N = *argv[1];
    }
    
    *array = (int *) realloc(array,N * sizeof(int));
    for(int i = 0;i < N;i++){
       *array[i] = i+1;
    }
    for(int i = 0; i < N;i++){
        printf("%d ",*array[i]);
    }

i have a quick question in python:

when doing
m, n = n, m%n

The "m" in "m%n" is the m before we affected it the value of n or after ?

[wispy bluff]

The m is the unaffected value

The explanation is simple, because we assign the value in a continuity and not separately the value of m does not change until the program has been executed.
For example :-
m=n

n=m%n

In this case we assign the values separately so the value has changed.

whats wrong in this code

the output is always 0.00000

[umbral sinew]

use %lf instead of %f when passing values to double variables with scanf

[rotund fossil]

yep , thank you

[umbral sinew]

also, in the volume calculation, 4/3 will evaluate to 1, so write "4./3" or "4/3." or "4./3." or cast it to double with "(double)4/3" to get the correct volume

volume = (4./3)* M_PI * pow(radius,3) ;
printf("volume is : %f ", volume );
return 0;
}

you can find the value PI in the library "math.h"

instead of "radiusradiusradius", use the pow(Basis,Exponent)-function

Thank you

[dull anchor]

is it easy to learn python?

[idle dew]

very

[dull anchor]

do u have a recommended book for beginners?

[idle dew]

In my view, every progamming languages got itself a documents written by it's developed team

None of those book i'd recommended better than original document. Because tutorials you seen on Internet are variant of these documents

https://docs.python.org/3/tutorial/index.html

[dull anchor]

oh wow thank you so much! this is so cool

im almost done with my accountancy undergrad and thought i should learn something

[umbral sinew]

Performance wise, writing radius * radius * radius is probably faster than calling the pow function. Not that it matters much here, just saying :)

Hello.
Could somebody help me with C++ code?

• What's going on? - I want to edit a specific line in a file (.txt), and i've tried using TempFile, but I can't get it to work, for some reason.
  For example:
  User enters Line 17 (Line which will be changed) - It asks User which text they want to replace it with and it gets replaced

But, I just can't seem to get the code working.

Have you opened it in write+read mode

[tender pilot]

Can You elaborate, please?

[brave forge]

When you open file using fopen(filename,mode)

In "mode" you should declare wether you want to write , read, append,write and read, or maybe all three

[tender pilot]

I'm using "Ifstream" and "Ofstream".
I need to open the file, and open a TempFile, which will have everything copied in it.
User will input a line which they want to rewrite, and everything below, and above that line will be copied into the TempFile.
When it comes to the line that user has chosen, replacement string will be written, instead of reading it from the file.
Original at the end gets deleted, and that TempFile becomes the Original.

The issue is - I can't seem to get it to work.

It's possible, since the file is small, to write it all into the memory at once - and just replace the line I need, but I do not know how to execute that.
