Well, that was a month. Congrats everyone who has reached the end, and thanks to everyone who has contributed solutions and advice.
Sometime in January I will create a megathread for visualizations. If anyone has any other ideas, happy to hear them, otherwise, take a well earned 11 month rest until next year :D
Hey that’s me! Congrats to everyone!
Yay, I made it in the screenshot! Thanks everyone, this was my first year and it was a lot of fun!
Made it in the screenshot and beat me :). Congrats on finishing, in my mind, that’s the hardest part!
It was nice to see some of the same faces (as it were) again from last year!
Also great to see more Haskell solutions, and props to those crazy enough to write in J and Uiua.
Congrats to everyone! Not first year, though first year of at least trying every problem. Burnout definitely got me by day 20 though, ha ha ha… There was a lot of ugly (readability a backseat to “code writing speed”), a lot of bad (don’t ask how long the test suite has to run for), but an occasional gem of good (my day 19 solution is some of the most dopamine from just writing code I’ve gotten. I’m only used to getting that much when it actually gets merged). I learned a little through the problems themselves, but I did learn a lot about writing
macro_rulesmacros by creating a test suite generator and a benchmark generator. I also picked up some useful Git knowledge like--allow-unrelated-histories, interactive rebasing,--name-only, and using the reflog to help recover data (don’t ask what happened on day 23). This year was a personal success. Till next year!I liked 19 as well. Adding memoization and seeing the runtime drop to near zero was so satisfying.
My main learning takeaway was that I am not fully aware of all the various inbuilt iterators in rust, so exploring those was quite valuable.
Nice! Though I’m not sure if I belong on the leaderboard. There were a couple solutions I had to look up spoilers / inspiration for. My first year, next year I hope to manage it with no need to check things.
I dont think that is cheating, its about learning, and seeking help/inspiration is a valid way to learn. As long as you aren’t just using an LLM or copying the code entirely, I think you belong on the leaderboard.
You’re right. And my library aversion definitely made it harder. I think the day I learned the most was day 19, the towel one. Seemed simple at first but I just couldn’t wrap my mind around it, looked at a few solutions and one of the dynamic programming one solutions just blew my mind. Took me an hour or so to just wrap my head around it and then once I understood it I was able to write that abomination I posted from scratch (well, without needing to reference what I studied).
