One can write code in the fast cp style way and also be able to write good clean readable code in other places

yeah, but in real life, good code style is almost as important

I would argue that overuse of OOP abstraction is bad programming habits and code style

Hey 😆

karmic sequoia
#

you're incentivized to code fast, not code well

earnest forge
karmic sequoia
#

sure, but it isnt within the scope of what was discussed

#

i need to go now baiii

slender ravine
#

Tbf, how long it took for leaderboard to fill up

#

For this one

gentle cape
#

i did the first problem

#

do we have a leaderboard

#

Here's the truth about competitive programming and good coding style: you can have fun doing competitive programming and be a professional programmer with good code style and more

slender ravine
#

It gives you the instructions

wary river
#

I'm about to drop the most noob-looking, stupid sounding question ever heard of on advent of code
where can I find the problem statement

normal dragon
#

Part of the 'challenge' of AoC is learning how to decode the strange story instructions into what you actually need to do.

wary river
#

i can't find it 😭

#

i can't find anything, I can only find about the advent of code itself

Competitive require fast and accurate logic thinking

So that the first line of input isn’t the number of inputs 😭😭😭

Why can’t they just be like codeforces

And if they end up getting a job as a professional programmer, then they're going to have to learn a whole new bunch of skills.

slender ravine

Imagine getting beat by people that ain't even going to be a professional programmer 🥴

I wonder they would get ban by aoc, but doubt tho

karmic sequoia
#

Please don't use AI / LLMs (like GPT) to automatically solve a day's puzzles until that day's global leaderboards are full. By "automatically", I mean using AI to do most or all of the puzzle solving, like handing the puzzle text directly to an LLM.

#

I brute forced subproblem 2 lmfao

slender ravine
#

Yeah, I remember that so ye

gentle cape
#

I did not want to do the O(n) solution

karmic sequoia
gentle cape
#

Sorry wait

#

I don’t think O n is possible

karmic sequoia
#

wait guys

#

O(log n) is possible for this question

gentle cape
#

O(n log n) for part 2

karmic sequoia
#

yeha

gentle cape
#

I think that’s the smallest you can get

#

Sort and then use two pointer

#

For the first part it’s also basically the same

#

Sort and then traverse

#

I'd like to remind y'all that this channel has a fairly strict no spoilers policy

magic scaffold
#

wait no

karmic sequoia
#

you can do O(n) where n is the size of the output for part 1 and 2

send answers to aoc and use timing to binary search the answer

gentle cape
#

Oh yeah

slender ravine
#

||Why would it not possible for O(n)||

gentle cape
#

It is

karmic sequoia

it is possible

aocd v0.1

dummy name to pull advent-of-code-data

Released on <t:1607168734:D>.

#

can't believe i got the package name wrong twice ... 😮‍💨

#

aocd is good as well 👍 #bot-commands message

hollow wharf
limpid grail
#

I'm going to be using this, making sure I only send one request per day :D


def get_aoc_input(day: int) -> str:
    day = str(day)
    aoc_inputs = read_aoc_inputs()

    if day in aoc_inputs:
        return aoc_inputs[day]

    response = requests.get(
        f"https://adventofcode.com/2024/day/{day}/input",
        headers=AOC_HEADERS,
    )
    aoc_inputs[day] = response.text
    write_aoc_inputs(aoc_inputs)

    return aoc_inputs[day]
#

If you want to get your AOC_HEADERS, go on to the site (make sure to reload it) and inspect it
Then go to the network tab and find the Request Headers

image.png
#

Toggle Raw mode, copy that text and ask CGPT to convert that to a Python request header

#

its working great 👍

hollow wharf
#

and ask GPT
bruh

limpid grail
#

Hey man, if you want to do it yourself go ahead

#

Not me 😄

#

But maybe the session cookie alone is enough to get

hollow wharf
#

I fear that one day this AI thing will become good enough that I won't be able to have this kind of reaction anymore because it'll just look stupid lol

limpid grail
#

It probably is, but anyways this works and im low on time

hollow wharf
#

Oh? Why are you low on time

limpid grail
#

I'm doing engineering

hollow wharf
limpid grail
#

we're going to pretend i didnt just not do that

#

umm almost

#

day needs to be used as a str since apparently json cant have ints as keys

#

yeah it works now 👍

peak dock
#

now make submit

limpid grail
#

i did that a while back by manually copying inputs lol

peak dock
#

no i mean a submit() function

hollow wharf
#

you can make submit the same way you did this

limpid grail
#

bru

hollow wharf
#

auto submit using a request

limpid grail
#

nah i want to feel it

#

i want to see the gold star pop up on my screen

#

i got inspired after i met someone in my uni (after talking with them in the uni discord) and they said they're doing AOC in Rust

#

but im just doing it, for funsies

#

maybe some of them ill optimize if i have time

hollow wharf
#

i know that feeling, its me from a year ago when i did aoc the first time

limpid grail
#

this is my third time trying aoc, i usually just get bored and stop lol

peak dock
#

the most recent activity in my uni discord was three months ago and that was a steam scam post

limpid grail
#

also it gets challenging at some point

limpid grail
hollow wharf
limpid grail
#

yeah maybe i wont be able to solve everything on the same day

#

wait can you do day 1's thing on the next day

peak dock
#

i only finished aoc the first year i did it

peak dock
#

theres no time limit

limpid grail
#

ohh

hollow wharf
#

yeah you can do any year and challenge anytime

limpid grail
#

will i still get stars tho

peak dock
#

yes

hollow wharf
#

yes

limpid grail
#

noice

hollow wharf
#

you just wont be on the leaderboard

#

or just will be so far

peak dock
#

not if you make a private leaderboard with just yourself

#

😎 👍

hollow wharf
#

easy 1st place

limpid grail
#

i dont think ill be on the leaderboard anywyas lol

#

if i do compete it'll be for performance

Good morning

hey

good morning

#

nuh

low condor
#

Shall I code in Python or Rust (I ain’t doing the roulette this year) - decisions decisions

thorn inlet
#

do both

limpid grail
#

umm finish in python first

low condor
#

Could do

limpid grail
#

get those stars

#

then do rust

hollow wharf
#

maybe try something except those

naive wharf
#

who pinged

limpid grail
#

if i try rust id learn something

low condor
#

For me this is less about the stars and about doing something new

#

So I’m going to force myself to always code using Vim modes this month

thorn inlet
#

for the "difference" you could use it yeah

rancid zealot
#

ooh

#

like im pure begginer so like i dont even know if my code is right

#

like i wrote all this

#

so do you have any suggestions

hollow wharf
#

also if you want to know if your answer is correct

#

just try

rancid zealot
#

are so any suggestions on thsi?

hollow wharf
rancid zealot
#

ooh ok ok

marble minnow
#

okay what. The question is either worded weirdly or i'm just tired cuz I just woke up

limpid grail
#

you're tired

#

:kek

marble minnow
#

yeah, most likely

limpid grail
#

read the story! its fun

marble minnow
#

i've read it, always do : )

#

could you explain one thing for me please?

#

oh okay

#

i was about to ask my question but then answer came to my mind

ocean grove
#

If I post a workingsolution, is possible for people to provide with tips to optimise my code?

sullen adder
slender ravine
#

should I try vimscript even when I have never used vim

hollow wharf
#

what is even vimscript x)

#

is that like the language to code vim extensions?

slender ravine
#

probably something that automate vim

wheat marsh
low condor
#

Am happy to help you with this when I finish today, if you'd like :)

#

shouldn't take too long - just need to learn rust first

karmic sequoia
#

can't you do aoc part 1 in O(n + log n)

#

answer: no you cant im stupid

low condor
#

I would suggest not posting this in here even for older days.
Do you want to make a thread in #aoc-solution-hints

hollow wharf
#

do people use libraries like numpy in aoc or is it generally just standard libraries only?

low condor
#

do whatever you like :)

#

it's deliberately set up that way

vagrant geyser
#

There have been some problems in the last years that nicely map to a series of matrix transformations, so yeah, numpy works well for some problems

low condor
#

sometimes I use networkx for upcoming path problems

hollow wharf
#

Looking at the first problem it's set up like a matrix from what I can see, so I'm kinda like why would I do matrix multiplication if I can just use numpy

||I'm got the basic logic down using abs but need to order the two columns to compare in order||

#

Nvm, just used ||zip||

To bypass it, used ||(l:=text_parsing_here)and sum(actual_calculation_here) || no semicolon, still one expression :3

bleak sable
# karmic sequoia wgut

If there are no nested loops, just loops next to each other, then it's O(n). Because even O(100n) is O(n)

karmic sequoia
#

O(1)

#

logick 100

bleak sable
#

You gotta find the answer first. See definitions of O, the constant multiplier or lower-O elements of the sum don't matter

does anyone have solutions to AoC in languages other than python?

lusty rover
brisk briar
#

oo

hidden pawn
#

in part 2, do they mean how many times a single digit occurs, or how many times that exact number occurs.
for example, with the number 39842: do they mean how many times 3, 9, 8, 4 and 2 occurs in the other list, or do they mean how many times 39842 occurs in the other list?

#

I'm a little confused on the wording 😅

peak dock
#

how many times 39842 occurs in the other list
this one

hidden pawn
#

ok! thanks!

unborn bloom
#

hope its fine, anyone who is struggling to learn python, you can DM me.

north lantern
#

Can someone help me with day1(python)?

#

For some reason the result is too high

#

Or do I really need to make it with 2 lists

thorn inlet
#

you could do it with a single list, but uh, you iterate over it in a really weird way, and you sorted the whole list when you should be sorting 2 individual rows
you take the first number, and the rest of them, then the second and the rest, ...

north lantern
thorn inlet
#

im not sure how did you even end up with this, it just doesnt make sense

north lantern
#

Yeah me neither

#

But how would I fix it

thorn inlet
#

i would recommend to use 2 lists and think a bit more on how to do the iteration

I made a little website to display the community's solutions to AoC questions (here) But according to the AoC about page:

Can I copy/redistribute part of Advent of Code? Please don't. Advent of Code is free to use, not free to copy. If you're posting a code repository somewhere, please don't include parts of Advent of Code like the puzzle text or your inputs. If you're making a website, please don't make it look like Advent of Code or name it something similar.

Should I take the website down? Or is it fine if I provide credit for the design to AoC?

rapid wolf
#

You can have the solutions, but you shouldn't be reposting the puzzles afaik

brisk briar
#

Got it, so I'll just replace the puzzles part with links to the aoc question?

rapid wolf
#

yea, that should be fine

nice little site

#

I am being serious I am not joking

#

Why lubricant?

low condor

how much does the difficulty scale for each day? i found the first day to be fairly straightforward, but i assume they get very tough at some point. pithink

low condor

Vimscript wasn't bad to code in actually

#

at least for day 1

low condor

still haven't done last years 24 part 2

oh wow

i suppose it is relative... i have 6 total stars 😅

if you're learning then it's all good

sullen adder
#

yes of course

low condor
#

also this screenshot reminds me I should renew my AoC++

#

#

There that's much better :)

#

I pay for this and for Nitro - which I need to post my not-so-code golfed solutions in this server

lusty rover
#

lol, !paste

low condor
#

yeah but where's the fun in that

lusty rover
#

Or just link the GitHub where they already are anyways

low condor
#

it's much more fun to make people scroll instead

lusty rover
#

I pay for Nitro just for the emojis

low condor
#

That is also a noble reason

#

I do like having separate profile pics

#

IRL friends sometimes get weirded out by my profile pic decisions on this server XD

they can get over it

Make sure you take some time to look at how others solved it and see if you see any new tricks you can pick up.

I was reminded of np.loadtxt() yesterday. There's always something new, or something you've forgotten.

Hello Everybody!

20 minutes to go for day 2!

native oak
#

hi guys

#

i need help w python smth

#

anyone on?

shrewd sentinel
native oak
#

so i have a link (my AoC day1 input) with the numbers right, i wanna somehow read the file and then use it to complete my code

#

would it be better to copy paste the data in a .txt file then use that in my code by open() and stuff?

#

sorry, i know im not being clear, im a very bad beginner to python, so I can't prompt properly

floral hare
compact wasp
floral hare
#

it's not like readable nor good to have per say a 1000 line string variable in your code would it?

compact wasp
#

code files should be used for logic

#

the 1000 line string variable is not that

floral hare
#

also looks like this year there's only like a few people who did the 2nd part?

compact wasp
native oak
#

okay guys thankss

#

stay on im gonna cook :>

compact wasp
#

with a name like inferno you'd better

native oak
#

how do I use github?

#

i wanna create a file for my AoC 2024

#

is that a good idea? how do I create one? (ive only made an account, idk anything else)

floral hare
#

(it's more said about in the about page)

native oak
#

wdym? post it for what

shrewd sentinel
#

im just gonna wait until the month is done

native oak
#

cuz if so, my code is horrible, I dont want anyone using this thing 💀

floral hare
native oak
#

I dont get what you mean sorry, whats the relation with the lb and github ??

shrewd sentinel
#

they just dont want people posting the solution so that others dont copy it

#

i think

native oak
#

ohh

minor cave
#

We don't want solutions posted in this channel specifically. This is a spoiler-free channel.
The overall Advent of Code policy is that no solutions are to be posted until the global leaderboard fills up.

#

oh sorry, ill delete my screenshot then

#

im sorry

You're welcome to post it in our spoilers thread (we have one for each day). If you're looking for help we have #aoc-solution-hints, where you can create a thread there or post more spoiler-y things (just not full solutions there)

Well, at least, better than yesterday

Perhaps this is a silly question but if the leaderboard for today does get cancelled (which it probably will) does the leaderboard aggregator understand that?

This isn't the first time there's been website issues and clearing the leaderboard just drops ... everything. It's not like he can reset it and start it over.

lone storm
#

Just wondering, how do people on the leaderboard complete it in like 2-5 minutes instantly? Is it just a lot of practice with puzzles like this or do they have other tricks for it

#

Talking about people who actually complete it without AI aid ofcourse

That’s how I’m thinking about it atleast. Without sitting down for it yet but just reading the question I know it’s gonna take me some time. But I also know how it’ll help me understand/learn more

guys someone did part 2 fast?

it took me like 15 minutes

when you clicked in part 2

#

like barely it started

#

doesnt it took a while?

woven oriole
#

does someone else use aocd lib for submitting

i do not, i mean, you're just saving like 3 seconds

Outside of puzzles like this

#

you could just extrapolate the AoC "story" scenario into a plausible real-world usecase

#

but comparing adjacent elements is fairly common. data analysis strikes as one such thing.

cyan sleet
#

I'm an introvert swede, how are you expecting me to smalltalk?

#

also for arch users trying to get the orphaned smalltalk package in the aur going, add this to the end of the prepare function in the PKGBUILD

  sed -i 's/\&inbuf/(void*)\&inbuf/g' packages/iconv/iconv.c
  sed -i 's/const XML_Char \* entityName)/const XML_Char \* entityName, int is_parameter_entity)/g' packages/xml/expat/expat.c
```this made it build for me
#

turns out some api details of libraries might have changed since...2015

magic oxide
#

making smalltalk read files took me a while

#

had conflicting information from different sources

modern terrace
#

i gave up on my smalltalk

cyan sleet
magic oxide
cyan sleet
#

ok, got file read/write working

magic oxide
#

I'm using GNU smalltalk tho so idk if that affects things

cyan sleet
#

I have a 🐈

f := FileStream open: 'input' mode: FileStream read.
f linesDo: [ :line | Transcript show: line; nl ]
magic oxide
#

I tried FileStream read instead of #read and it kept erroring

#

still have no clue why

cyan sleet
#

and yeah, I had to patch GNU smalltalk to even compile on my system 🥴

magic oxide
#

wait does nl on transcript give you newlines

#

all I've seen in the docs is cr

cyan sleet
#

idk

magic oxide
#

yeah I used that too

cyan sleet
#

now, how do I work with strings? 🥴

#

(I guess I could read char by char and write my own integer parsing)

low condor
#

Is gnu small talk what people are using?

magic oxide
#

yeah

cyan sleet
#

we yes

#

people actually doing smalltalk probably use squeak or similar

low condor
#

I see there’s also something called Squeak

#

Right

magic oxide
#

from what I've read smalltalk is kinda built to be used with a GUI or smthing

#

which is what squeak or pharo is? I think

#

I just homebrewed gnu smalltalk

low condor
#

A GUI? Damn

#

I’m on GNU/Linux is it just there or needs to be downloaded

will the lb be cancelled today

I really think it should (but I hope not...)

#

Feel more like fast typing, I know exactly what I want to do but still took like 7mins

#

For first part

cyan sleet
#

it's not much typing

dim pivot
slender ravine
#

No clue how people can do it in 2mins

dim pivot
#

for yesterday's it was ||unpacking 2 lists, sorting them, and then doing some basic operation||

slender ravine
dim pivot
#

I'd definitely say it gets more interesting in the later days though

slender ravine
#

Today is ||sort the list in ASC and desc and compare, then check abs value||

dim pivot
slender ravine
#

Which I know immediately but It took me few mins to type the solution

dim pivot
#

There was a method involving ||polynomial interpolation||, but I used ||math to figure out a formula and had a lot of constant factors||

slender ravine
#

So how someone got it in 2mins 💀

dim pivot
modern terrace
slender ravine
#

Precisely 66 seconds for first star 💀

dim pivot
#

Like in pythoon ||there's a trick using zip to generate the pairs automatically||

slender ravine
#

I bet I was restarting my ide at that moment, or reloading to see the question

slender ravine
modern terrace
#

your first mistake was to use an unreliable IDE

dim pivot
#

Idk I always find an ide much easier

#

Otherwise I might forget how to exit vim

#

I also don't like using extensions to get the input or submit

#

Because sometimes these don't work and then I lose my lb place

cyan sleet
#

that was 5 minutes, so a bit slow

I also didn't check that it runs at all 🙃

https://en.wikipedia.org/wiki/Smalltalk

Smalltalk

Smalltalk is a purely object oriented programming language (OOP) that was originally created in the 1970s for educational use, specifically for constructionist learning, but later found use in business. It was created at Xerox PARC by Learning Research Group (LRG) scientists, including Alan Kay, Dan Ingalls, Adele Goldberg, Ted Kaehler, Diana Me...

strange zinc
#

Will have a look later. Where did ppl get it from? Looked at something called squeak

cyan sleet
#

I ended up using gnu smalltalk, which I had to do some patches to to make it compile on my machine 🥴

#

tbh, when you get the initial "oh god what is this" it's not a bad language

#

decently ergonomic

#

just quite different from any C like language

#

fwiw, smalltalk also usually isn't even file based

#

gnu smalltalk allows that

strange zinc
#

fwiw?

cyan sleet
#

for what it's worth

#

I did not want to try to dig into smalltalk images and the vm 🥴

strange zinc
#

Think I'll just stick to python

cyan sleet
#

the fun of the roulette is that you get to experience a lot of different takes on programming

#

some parts you'll like and learn from
some parts you'll hate with a burning passion

strange zinc
#

True. But comfort > trying out stuff

#

I like reading other people's solutions.

Formatting code on Discord

Here's how to format Python code on Discord:

```py

```

These are backticks, not quotes. Check this out if you can't find the backtick key.

For long code samples, you can use our pastebin.

Fastest as in?

My fastest time was 2021 day 1 where i completed both parts in 00:08:13

#

But if you're looking for runtime, eh i don't care enough to crazy optimize

low condor
#

My fastest time is... checks notes ... 02:36:12. Consequences of having the puzzles start at 5am for me

rich imp
#

no i mean like the fastest to run

#

as in runtime

#

or maybe yall dont do that here idk

unique osprey
#

I'm sure some people do

minor cave
#

runtime isn't really something we check because it really depends on the system you run it in

some of the early problems are so simple that the runtimes there are just not worth measuring

I have like 1-2 more not-quite-languages on the list, but nothing eso really. My minimum standard is the language needs to be able to read in input somehow and esolangs don't always hit that mark

slender ravine
#

My solution including automatically submitting the answer so definitely >1ms

cyan sleet
ivory marsh
# weary topaz can it even read files?

It can take a char/num of input, I've just assumed for esolangs that the input is put into stdin, since almost all have some sort of "read one thing from stdin" instruction

cyan sleet

I also have hopes for postscript
