An unofficial home for the advent of code community on programming.dev!
Advent of Code is an annual Advent calendar of small programming puzzles for a variety of skill sets and skill levels that can be solved in any programming language you like.

Rules/Guidelines
- Follow the programming.dev instance rules
- Keep all content related to advent of code in some way
- If what youre posting relates to a day, put in brackets the year and then day number in front of the post title (e.g. [2024 Day 10])
- When an event is running, keep solutions in the solution megathread to avoid the community getting spammed with posts

Nix, because I hate myself. No, it is very much not made for this purpose. But it's possible to use if for this.
I've seen a couple people attempt this. Am very curious about how exactly that will be done. Although I'll have to say that i've seen far worse and/or more difficult submissions. People cook up absolutely insane code
True. I love how AoC is a hotbed for creative and/or insane ways of solving coding problems.
If you wanna check out how it goes in Nix: https://git.sr.ht/~kintrix/aoc2024
I've started with Go, but I think I've realised AoC isn't for me. I feel so incredibly dense.
That's fair if you aren't having fun, but I wouldn't write it off completely. Like I only made it to day four last time.
The problems they present are of a totally different class to what most programmers will ever encounter in the "real world."
Once you get more used to the style of the problems (data structures and algorithms (DSA), like what you might see on leetcode), then you honestly start to have fun with them.
I really struggled with DSA until recently, so if you'd like some help I would be happy to give you some pointers.
Thanks. I felt very deflated after struggling with something seemingly so simple. I was using Go and couldn't figure out part 2, at least without nesting loops three layers deep.
Today I decided to try to learn Elixir instead and allowed myself some assistance from Claude.ai, which was much more fun.
Nesting loops is indeed the first intuition anyone would have to that problem. The only reason I knew to use a hashmap data structures is because I practiced on exactly these kinds of problems, and looked up explanations and answers on the most basic stuff imaginable.
I felt very deflated after struggling with something seemingly so simple.
Definitely not simple. Especially without training in DSA. You shouldn't expect yourself to spontaneously invent efficient algorithms to problems that have been stumping students for decades.
Try it out yourself for maybe 30 minutes, then do yourself a favour and look up a good explanation to solving it.
My hope for this year is that we can help eachother understand and solve these problems. I'd love to find some good "editorials" on each problem, breaking them down in detail.
Yes, I guess I held myself to too high expectations. I haven't even studied CS and learned programming on my own... I've been trying to do some exercises and a few courses on algorithms but of course that can't be compared to going to university. Thanks for the tip, I won't spend hours in frustration in the coming days for sure. Maybe I should post my attempts even though they are incomplete or fail, to spark discussion.
I would love to see some attempts and discuss alternatives, improvements, etc
After solving puzzles and seeing other peoples' elegant solutions while mine feels brutish and ugly (even if our approaches use the same algorithm, mine is inevitably less elegantly-implemented), I also feel too stupid for AoC sometimes.
But hey, I am never going to get less stupid if I don't try, and solving problems the ugly way is still a solution. I have fun doing it.
But if it's not just the comparison to others ruining your fun, if it's that you inherently do not find this activity enjoyable, don't force yourself!
I've got a really nice setup with benchmarks, auto-input-fetching and solution upload and such, written in Rust, so I'm sticking with that. I kinda wanted to try Odin, but december really snuck up on me, and I didn't have time to set it up or really get familiar with it.
Iterators and slicing and such are all just... so nice for parsing streams.
Still going with C as my main language with the 'straight to the point', data and array centric style that's worked well before. Perhaps see if I can get some of it running on Turbo C again. Also fiddling around with JavaScript now for list comprehension variants and was eyeing Elixir but that's probably not happening this year.
I’ve solved the first two in Rust, and will likely keep going until I can’t anymore, just like with previous years. It’s a fun language, and i’d love some practice too
My „comfort language“ Kotlin and Python, because I really got to refamiliarize myself with that language. I probably won‘t have the time to do much more than that, but if I do, I‘d love to try to solve the problems with a Minecraft datapack.
Julia, since I used it for some projects this year but never for something "time critical" like AoC with a new problem each day. I really like that it's simple like python but with strong typing. Originally I wanted to use Ocaml to learn it, but on day 1 I realised I don't know how to do anything in it yet 😄.
Python
Not my first, second, or third choice. But I’m in between moves and have very limited access to my desktop (even remotely/SSH) so I need the simplest tool for the job.
I feel kind of silly working on my 100 line implementation, where someone will just Python up a 3 line solution and call it a day. It's definitely a good tool for the job.
I don’t think you need to feel silly. Programming languages are tools. Some are better suited for jobs than others.
AoC is good for two skills:
- Learning how to solve problems.
- Learning how to process and model data.
With python #2 is no longer difficult. In the past I’ve used Rust or C and I spent way more effort on #2 than #1.
I think the key is what is your goal in doing this? I like the puzzles but have limited time so I use python to solve them quickly and be on my way. If I had more time i would have liked to learn / try go this year.
I always default to ruby, even though I want to learn tons of other languages. Sometimes I do it in multiple languages, I might try Elixir again.
Ruby is such an enjoyable language to write it. It really feels like they thought about the developer's experience when designing that language
I was doing vanilla JavaScript and using code sandbox, because I was doing it with my coworker.
But now I'm considering switching to Typescript.
TS is a great way to write JS, and one of the nice things about it is you get to choose exactly how much of it you want to use.
You can even just change your file extension from js to ts, compile it with tsc file.ts or run it directly with tsc-node file.ts.
C++ because I forgot to plan for anything else, so I'm just reusing what I had from last year
Going with rust for the second year, I'm still trying to learn things with it and AoC is a great way to do so
Typescript with Deno. Was thinking of trying Gleam but I don’t know if I’d have the time to do it in a new language and Deno is just so nice anyway lol
I've enjoyed Deno in the past. Similarly, I've heard good things about Bun, though haven't used it myself.
I'm trying F#. I normally work in C# with LanguageExt to make C# more functional.
Factor!
I've tried using vyxal 3, and while I was able to solve day1 part 1, part 2 still eludes me. I know what I have to do but I haven't been able to coax the language into doing what I want it to, probably because it's a wholly different paradigm from praclangs.
Golang, just for learning a new language. But I’m a bit time constrained so I don’t expect I’ll be able to complete every day.
Java
R, because I’ve already used Python, VBA, and Excel formulas.
Been trying to pick up zig, so made sense to try the AoC with it as well.
Nim, because it's fast and expressive.
