   🎄 [/AoC/] Advent of Code 2024

   This thread will keep track of my progress for Advent of Code 2024. Solutions will be spoilered.

   Language: Rust (this is my first time with the language so forgive any non-idiomatic code).

     between this and day 21, I was very close to giving up on this year's AoC.. I had to learn some digital electronics basics to even come close to figuring out part 2 in a reasonably efficient way.

     It was refreshing how easy this day was. The second part was just it checking if you had completed all the other days' two parts.

     This is definitely not the most efficient way to do part 2, but it ran in under 20 seconds which I can live with.

     This one was pretty fun to implement. I got some experience with defining iterators an idiomatic way, in this case for all the edges adjacent to a node in a graph.

     I finished this some days ago but never got around to poasting it.. I spent way too long trying to brute force it and running into edge cases for part 2, and nuked my old solutions with something much simpler

     This was the last problem I had left to finish and while I initially thought it was niggerlicious when I first read the problem, I felt like taking that back after finishing part 1... Then I saw part 2, and realized it was in fact very niggerlicious.

     The rust docs for a binary heap had an implementation of djikstra shown as an example which felt a little like cheating since I didn't have to figure out an idiomatic implementation from scratch..

     part 1 was fun. part 2 took a lot planning on pen and paper... I dont think my solution was fully general either..

     this felt pretty nice since I was able to reuse a bunch of code (dijkstra) and also abuse functions returning options to shorten the syntax by converting unwraps into question marks

     I accidentally solved part 2 while trying to do part 1 without realizing it so i don't have separate functions for the two parts.

     For a while I was getting filtered by part 2, but then I came across a hint that that the number of vertices of a polygon equals the number of sides (for polygons, start with a triangle and then use induction, and here we are just combing squares...) which made this easier to solve. Also helpful was printing out the grid but color-coded (pic 2 shows a test case).

     tried to make main shorter since the rest was longer.. I couldn't figure out a clean way to do this with only iterators and no explicit loops (but loops are just syntactic sugar for iterators here so it kind of works)

     @hazlin Sure, the text is too large for a single poast, so I'm poasting three files: the prompt, the test input (same as your screenshot), and the actual input (which I believe is randomized for different users). the answers to test.txt and input.txt are in the prompt file itself.

     @karna @hazlin I’ll look at it when I get there, for now I don’t want to spoil the solutions. My initial plan was to use 25 different languages I don’t feel confident writing or don’t know at all, but now I kinda want to continue using haskell because there’s potential for something incomprehensible even for day 2

     @Inginsub @hazlin oh i didnt do the APL stuff this year, it was 2022 I think, so no spoilers there (unless you are saving 2022 exercises for another day too). This year I tried rust as my unfamiliar language of choice (I typically pick an unfamiliar language and do aoc for a specific year with that). Doing 25 entirely different languages sounds like it would be either very fun or very annoying by the end of it.
