FichteFoll's Advent of Code

These are just my (quick and dirty) solutions to the Advent of Code Advent calendar for everyone to see, frown and laugh at.

Code is split into folders or files by year and day with my input included for better reproducibility. I did not complete all puzzles, so you'll only see those that I completed.

For 2017, wanted to use Rust, which I had barely used until that point, and not use any external crates. Unstable and experimental features were allowed.

For 2018, I again used Rust because I like the language a lot but don't have any real uses for it considering my day-to-day language is Python. I'm unsure whether I'll allow external crates this time, but unstable is definitely allowed. Crates are too useful. Also, tests are nice.

For 2019, I decided to go with Haskell. That was definitely an interesting and fun choice, although implementing some solutions definitely took a bit longer than necessary. For some days, I used the Linear package for its vector implementation, although that was definitely not necessary. The RecordDotNotation extension was added later, but I would definitely have liked to used that. I eventually gave up after spending a lot of time on day 18, which I built a correct solution for but could not for the life of me get performant enough, despite implementing every optimization strategy I could think of or found from discussions.

For 2020, I am going back to Rust, because it has been two years since I last did something with it.

For 2021, Rust it is. It's just so much fun.

It's 2022 and you know the deal (Rust). It might sound boring, but I distract myself from "too much Rust" (if that's even possible) by comparing mine against other solutions in a different language. You can read more details and a summary in the subfolder's README.

Completed

The following completed counts are a snapshot of the respective year before the end of December (though until now I have not gone back to a previous year anyway).
