[strange turret]

yea

[violet vortex]

whats cs

[stone ice]

oof....

[violet vortex]

cursor?

[strange turret]

yea context matters

cs is computer science

[violet vortex]

oh

[strange turret]

anyway

[stone ice]

Computer Sceince

[violet vortex]

yeah its my first ever college class of cs

ik how to use windows and game but not coding

[strange turret]

use this for now

[violet vortex]

ill put it in the comments

i can do both easily (now)

now

[strange turret]

this is probably the way that your teacher wants, just if x == "a" or x == "A" should be fine (for now)

do you want to move to the third question?

[jovial sail]

to my knowledge context is they in first week of python if not newer

so im not surprised at all at them not knowing functions

[violet vortex]

its my fourth day

[jovial sail]

ur : are messed up but u getting the spirit

[violet vortex]

trying to get the least red possible on my screen

[strange turret]

you want to add the salutation = "madame" for each of these conditions

[violet vortex]

yup

:DDDD

i finally did it

and i understood what i did

[strange turret]

you forgot the colons

:

[violet vortex]

oh yeah

idk where to place them

i know where theres 1 condition but not 2 on one line

[strange turret]

what do you mean?

[stone ice]

the color was on the end of the line with "if"

colon*

[strange turret]

you can delete the code above, the ones that use in

you will get your chance to make use of in in the future

[violet vortex]

yeah

but i still wanna leave it there as notes

[strange turret]

comment those out by selecting all the code there and pressing Ctrl + / on your keyboard

[violet vortex]

yup

my teacher told us abt that too

really useful

can we do the binary one pls

[strange turret]

it is probably a good habit to add a new line

[violet vortex]

ive been awake since too long

[violet vortex]

yeah

[strange turret]

go on

[violet vortex]

im confused when to put a semi colon on the else

i forgot that time but i always make a new line

[strange turret]

you dont use semi colons in python

[stone ice]

colon*

[strange turret]

what's the third question

[violet vortex]

@strange turret

[violet vortex]

i meant that

my brain is dying rn but ik u use colong lol

mb

[stone ice]

"user's right" 😭

[violet vortex]

ey

thats how its literally translated

user's previlege

?

[stone ice]

this one makes more sence

[violet vortex]

ye mb

[stone ice]

or "rights"

[strange turret]

user's right are typed on a 4 bye binary number every right is encoded in binary they gtive acess to a specific module

1-RH
2-inventory
4-compatibility
8-computer science

Tests:

with 0b1011:

acess to RH moduel

acess to inventory moduleacess to computer science module
with 0b0000:
acess to none of hte module
with 0b0100

acess to compatibility module

this is a wild question to give a beginner

[violet vortex]

i knew how to translate from base 16 to base 2

if that can help

[strange turret]

perfect

[violet vortex]

id have to pull my notes but i get teh gist

so what do i start with

i have NO clue

[strange turret]

what is the method your teacher taught for converting bases

[violet vortex]

hmmmm

i forgot but uh

if i remember you use modulo

or smt

ik you use modulo to do divmod

[strange turret]

wow

that is wild, i thought they will go the easier method

but anyway

[violet vortex]

5 % 4 = 5

4 % 5 = 1

[strange turret]

can you write out a program to convert a number from base 16 to base 2

[violet vortex]

no

uh

yeah i have NO clue

[stone ice]

how your teacher teach it

[violet vortex]

uh

id have to pull my notes out

but

ik that it works with the power of 2

1000 = 8

for example

ik hexadecimal

a bit

[stone ice]

show some basic program that will convert it

[violet vortex]

i would have to look at my notes

i dont know how

[stone ice]

also kindly put words on single message

[violet vortex]

alright

not doing this to annoy anyone lol its out of habit i just type how i tell sentence

[strange turret]

test = 0b1000
print(test) # 8

is this the method your teacher taught?

[violet vortex]

yeah he showed that

not how to convert or anything

[strange turret]

hmmm

[stone ice]

thats a literal value.... thats not converting anything

[strange turret]

you get what i meant

remember, beginner python

from part of the question
with 0b0100 -> access to compatibility module

do you know what this means?

[violet vortex]

no

probably a value thats equal to accessing the compatibility module

i think b = 11

in hex

[strange turret]

essentially you can think of it like this

0b1000 -> lets you access the computer science module
0b0100 -> compatibility
0b0010 -> inventory
0b0001 -> RH

so far so good?

[violet vortex]

yes

so i gotta translate those hex number into real values?

[strange turret]

0b0010 -> inventory
0b0001 -> RH
0b0011 -> inventory + RH

makes sense?

[violet vortex]

oh you added them up

why tho

[strange turret]

correct

[stone ice]

if you type it on python it would automatically convert into decimal

[strange turret]

thats what the question is giving you as a problem

[violet vortex]

i didnt know there was a question

[strange turret]

this is the problem statement

[violet vortex]

/genuinely

[strange turret]

is this not the third question?

[violet vortex]

it si

it is

even in french there wasnt a question just statements

[strange turret]

0b1001 what would this give access to?

just as a small test

[violet vortex]

only rh???

[strange turret]

look closely

it's 1001

[violet vortex]

yeah

uhhh

oh wait

a byte = to an acess

[strange turret]

0b1000 -> lets you access the computer science module
0b0100 -> compatibility
0b0010 -> inventory
0b0001 -> RH

for reference

[violet vortex]

thanks

alr so

cs module and rh

[strange turret]

correct

[violet vortex]

how did u know 0b0001 was rh

only

[strange turret]

in the statement

you sent

[violet vortex]

oh so

[strange turret]

the 1 at different positions refers to access to different modules

[violet vortex]

0b1011
the first 1 starting from left to right is rh
2nd is inventory
3rd is cs
4th is compatibility

[strange turret]

yup

[violet vortex]

IM STUPID.

[strange turret]

actually wait

0b0001 = 1 in decimal -> RH
0b0010 = 2 in decimal -> inventory

it's right to left

[violet vortex]

okay

so whats even the question

how do get every right?

[strange turret]

given a number 0bXXXX, calculate which modules you have access to

[violet vortex]

sending my whole file incase i lose it

[thick marten]

Click here to see this code in our pastebin.

[violet vortex]

what is the number they give

we didnt read the same text lmao

do i just type out every single combination?

[strange turret]

no

you just save it in a variable

access_code = 0b1011

or something like that

ok so now

[violet vortex]

i just dont understand the goal im working toward

[strange turret]

given any access_code

which could be something like 0b1011

calculate the modules you have access to

[violet vortex]

idk whats the acess code

[strange turret]

print out the modules you have access to

[strange turret]

the access code is variable

it's the thing the user feeds into your program

we dont know what the access code is

we are suppose to write a program that takes any access code and process it into the modules

makes sense?

[violet vortex]

0b1001 = RH
0b1010 = Inventaire
0b1011 = Informatique
0b1111 = compatibite

[strange turret]

follow my train of thought

[violet vortex]

ohhh

yes

sorry

[strange turret]

ok now i want you to notice one thing

0b1000 = 8  in decimal = has access to Informatique
0b1001 = 9  in decimal = has access to Informatique and RH
0b1010 = 10 in decimal = has access to Informatique and Inventaire
0b1011 = 11 in decimal = has access to Informatique and RH and Inventaire

[violet vortex]

yeah?

[strange turret]

these are all >= 8 in decimal right?

[violet vortex]

yes

[strange turret]

0b0000 = 0 in decimal = has access to
0b0001 = 1 in decimal = has access to RH
0b0010 = 2 in decimal = has access to Inventaire
0b0011 = 3 in decimal = has access to RH and Inventaire

these are all < 8 in decimal

notice that you no longer have access to informatique

[violet vortex]

yup

[strange turret]

correct?

[violet vortex]

yeah

[strange turret]

so we can form an idea right now, >=8 has access to informatique, < 8 has no access

we dont know whether it is correct for all modules

we just know that it is correct for informatique

[violet vortex]

wait but both of ? 8 and < 8 has acess to rn and inventaire

[strange turret]

but thats not what we care about right?

[violet vortex]

true

[strange turret]

the difference that we are can spot is the informatique is controlled strictly by >= 8 or < 8

[violet vortex]

so informatique = 8?

[strange turret]

we dont know yet

for the other modules

it might not be true

[violet vortex]

alright

[strange turret]

so let's try it with another module

0b0001 = 1 in decimal = has access to RH
0b0011 = 3 in decimal = has access to Inventaire and RH
0b0111 = 7 in decimal = has access to Comp, Inventaire and RH

all of these have access to RH

[violet vortex]

oh so as long as there's a 1 in the decimal we have acess to rh?

[strange turret]

0b0000 = 0 in decimal = has access to nothing
0b0010 = 2 in decimal = has access to Inventaire
0b0110 = 6 in decimal = has access to Comp, Inventaire

1, 3, 7 vs 0, 2, 6

[violet vortex]

oh man this is hard

[strange turret]

is it clearer now?

what does 1, 3, 7 have in common

but 0, 2, 6 dont

[violet vortex]

odd number

[strange turret]

correct

how do you know if a number is odd or even

in code

[violet vortex]

uh

odd = 1
odd = 3
odd = 7

(im joking they always end with 1 in binary code)

[strange turret]

do you know what is 1 % 2?

[violet vortex]

1

thats why its odd in binary

[strange turret]

how about 2 % 2

[violet vortex]

0?

[strange turret]

yup, 0

how about 3

[violet vortex]

3 % what

[strange turret]

3 % 2

[violet vortex]

1

oh

[strange turret]

4?

[violet vortex]

4 % 2 = 0

[strange turret]

notice something?

[violet vortex]

yes

i noticed it

we learnt that in math class

i think

[strange turret]

so we now know

there is a number that we can % with

in order to check if a number if even or not

that number is of course, 2

[violet vortex]

yeah

bcz binary

[strange turret]

the % 2 lets us check if we have access to RH

and RH corresponds to 1 = 0b0001

[violet vortex]

rh is 9 so its odd

oh you mean the ending digit

[strange turret]

if 0b1001, which is 9, 9 % 2 = 1 so we have access to RH

[violet vortex]

ohhhh

[strange turret]

and so

do you think we might be able to do the same for informatique?

[violet vortex]

yes

but it would be even

[strange turret]

of course we cant use % 2

[violet vortex]

odd and even?

[strange turret]

we need to find another number

[violet vortex]

idk if its called even number

[violet vortex]

8why

[strange turret]

checking if %2 = 1 corresponds to RH

not informatique

[violet vortex]

ohh

is that how you know rh is 1

[strange turret]

yes

[violet vortex]

informatique is 8

[strange turret]

yes

[violet vortex]

cant u just use 4

or 2

[stone ice]

thers simpler way, its called masking where you reject all bits and get some part of it

[violet vortex]

meu

[stone ice]

like 0bxx00 where x will be rejected

its simpler

[violet vortex]

i learnt like 2 days ago that binary number worked with power of 2

and how to count is hexadecimal

[stone ice]

masking is way easier than power of 2

[violet vortex]

i dont know what masking is

[stone ice]

look at this

[violet vortex]

oh my god thats so cool

[stone ice]

wait...

[violet vortex]

if only i could understand whats going on

[stone ice]

wait what...

..... why....

[violet vortex]

so how do i even solve it

[strange turret]

print(0b0010 % 4) # 2
print(0b0011 % 4) # 3
print(0b0110 % 4) # 2
print(0b1110 % 4) # 2

these all have access to Inventaire

[violet vortex]

ohhh

[strange turret]

print(0b0000 % 4) # 0
print(0b0001 % 4) # 1
print(0b0100 % 4) # 0
print(0b1100 % 4) # 0

these all do not

notice a pattern?

[violet vortex]

the second one has 1 as a decimal

[strange turret]

print(0b0110 % 8) # 6
print(0b0111 % 8) # 7
print(0b0110 % 8) # 6
print(0b1110 % 8) # 6

these all have access to comptabilite

[violet vortex]

compatibility is 4

[strange turret]

print(0b0000 % 8) # 0
print(0b0001 % 8) # 1
print(0b0011 % 8) # 3
print(0b1011 % 8) # 3

and these dont

do you notice a pattern?

[jovial sail]

what in the silly binaries we doing, why is there % here

[violet vortex]

my brain is beyond fried

i cant understand whats going on but at the same time i do a bit

[stone ice]

modulus 🙄

[strange turret]

haha thats why we are looking at patterns

the patterns let you spot things

so you dont have to rely on pure maths

[stone ice]

do you atleast know what modulus is?

[violet vortex]

yes

[stone ice]

what is modulus?

[violet vortex]

holy flip

hold on let me think of how to explain

the rest of a division like u did in 4th graade

[stone ice]

i just wanna make sure you know the stuff you working on

[violet vortex]

i know whats modulus but i cant explain it

yk the divisino you did when u were younger

its the rest of it that is the answer to the modulus

4%5 = 1

[strange turret]

print(0b0110 % 8 // 4) # 1
print(0b0111 % 8 // 4) # 1
print(0b0110 % 8 // 4) # 1
print(0b1110 % 8 // 4) # 1

print(0b0000 % 8 // 4) # 0
print(0b0001 % 8 // 4) # 0
print(0b0011 % 8 // 4) # 0
print(0b1011 % 8 // 4) # 0

can you see the pattern now?

[stone ice]

i hope this person know the order of operetion...

[violet vortex]

they both have acess

[violet vortex]

i do

[strange turret]

access to what?

[violet vortex]

informatique and comptability

[strange turret]

the first 4

what modules do they all have in common

[violet vortex]

inventory as wel?

even

oh

i see

[strange turret]

print(0b0110 % 8 // 4) # 1
print(0b0111 % 8 // 4) # 1
print(0b0110 % 8 // 4) # 1
print(0b1110 % 8 // 4) # 1
       # ^ look at this bit
print(0b0000 % 8 // 4) # 0
print(0b0001 % 8 // 4) # 0
print(0b0011 % 8 // 4) # 0
print(0b1011 % 8 // 4) # 0
       # ^ look at this bit

is this clearer now?

[violet vortex]

ohhh ui u see

odd vs even

yes i see!

[stone ice]

thats just masking with extra step.....

[strange turret]

but hey, letting people discover stuff on their own is fun

[violet vortex]

yes

ima learning

and not copying

[strange turret]

print(0b0001 % ? // ?)
         # ^ RH
print(0b0010 % ? // ?)
        # ^ Inventaire
print(0b0100 % 8 // 4) # <- this was the one i gave you the answer to earlier
       # ^ Comptabilitie
print(0b1000 % ? // ?)
      # ^ Informatique

fill up the question marks

so that all 4 lines print 1

[violet vortex]

hm

alr

the first one is 1 bit 2 bit 4 bit 8 bit

in order but

1 % 2 = 1?

[stone ice]

yes

[violet vortex]

1 % 2 // 1 = 1

[stone ice]

1//1 = 1 yes

[violet vortex]

whatw as i supposed to put

[strange turret]

you are suppose to spot the pattern and fill in the question marks

[violet vortex]

sorry im trying my best

[strange turret]

the question marks in this

[violet vortex]

line 5 = 2

?

[stone ice]

if you read the message of zehata youll find the patern

[violet vortex]

trust me im reading it

[stone ice]

copy the message she sent and fill the ?

[strange turret]

print(0b0110 % 8 // 4) # 1

[strange turret]

well

[violet vortex]

I GOT IT

[strange turret]

do you want to check?

in your code?

do you know how to solve the question now?

[stone ice]

do this
!e
```py
code()
```

the python bot will run it for you

[strange turret]

wait wait wait

[violet vortex]

!e

print(0b0001 % 2 // 1)

[strange turret]

dont go that far yet

[strange turret]

nice

[stone ice]

very well

[strange turret]

before you get here

let's write out the conditions first

[violet vortex]

oh right

[strange turret]

if access_code % 2 // 1:
  print("???")

what should we print?

[violet vortex]

depend on the acess code

??

[strange turret]

the access code we dont know

that's the whole point of the program

it takes some access code that the user types in

[violet vortex]

1248?

is the acess code>

[strange turret]

hmmmm

[violet vortex]

i just dont get why we doing all the modulo stuff to find numbers

i know how to but not why

[strange turret]

that's just what the question is asking you to do

this is just a learning exercise

[violet vortex]

i just dont understood how you went from random bytes to translating codes to answering the question

but i understood what the numbers meant at one poitn

[strange turret]

the question is asking you to write a program right?

the user enters an access_code of their own choice

that we don't know

[violet vortex]

ohh

[strange turret]

use this fact you already figured out to write out some conditions

print(0b0001 % 2 // 1)  # 1 -> has access
print(0b0000 % 2 // 1)  # 0 ->  no access
         # ^  this bit controls RH access
print(0b0010 % 4 // 2)  # 1
        # ^ Inventaire
print(0b0100 % 8 // 4)  # 1
       # ^ Comptabilitie
print(0b1000 % 16 // 8) # 1
      # ^ Informatique

this was what you figured out
EDIT: see my comments in the code

[violet vortex]

uhhh

im not sure

if (0b0001 % 2 // 1) = 1:
print( has acess to RH)

??

[strange turret]

you got the spirit

[violet vortex]

wait

[strange turret]

if access_code % 2 // 1 = 1, then we have access to RH

remember, we dont know what the user entered

[violet vortex]

oh

[strange turret]

we are probing what it is with our % 2 // 1

and we are checking the result =1

to determine if we have access

[strange turret]

comparison is ==

not =

[violet vortex]

do i do it with every other digit

[strange turret]

yup. basically

[violet vortex]

theres like 8

[strange turret]

4

[violet vortex]

?

[strange turret]

there are only 4 modules

[violet vortex]

why not 8 cauz 8 possibilities

[strange turret]

but you can use else

[violet vortex]

OH.

[strange turret]

1 if else for each module right?

so 4 if else

[violet vortex]

yes yes

i get it

wait not 2?

[strange turret]

you have 4 modules dammit xD

[violet vortex]

im sorry 😭

[strange turret]

how do you check 4 modules with 2 if elses

you need 1 if else for each module right?

[violet vortex]

%

% 2

[strange turret]

why?

[violet vortex]

bcz its going to be 0

?

im going to get burned to death lol

[strange turret]

no. i am describing how many if else block you need

[violet vortex]

2

bcz if its not 1 its 0

[strange turret]

the question is solved

you dont need any more math

why are you doing math?

[violet vortex]

uh

[strange turret]

if code_acess % 2 // 1 == 1:
  print("has access to RH")
else:
  print("has no access to RH")

[violet vortex]

thats literally what i did lol

[strange turret]

this is 1 if else

you need 4 of these

1 for each module

[strange turret]

this is RH

you should know how to write the other 3 right?

[violet vortex]

for yes

[strange turret]

nice

[violet vortex]

could you resume what we did

[strange turret]

anyway

[violet vortex]

cauz im going to note this

[strange turret]

i actually gtg

[violet vortex]

that makes sense

its 3am

but if you have time tomorrow it owuld be really cool

[strange turret]

haha cya go to sleep now

[violet vortex]

thank you so muc hagain you have insane patience

thanks for helping me

gn!!

[violet vortex]

Yeah I’d love you re explain it to me rq I get the base idea but not everything

If you have time tomorrow you already helped me so much

I understand the bits but what I would’ve done alone I would’ve tried out every single combinaison and did 15 if lol

I’d like to understand your method later IF you have time and IF you want

I can’t say how much I’m thanking u lol gn

[idle bobcat]

What help do you need?

[violet vortex]

I didn’t understand the whole problem but I’ll get back to it tmr

[violet vortex]
