I am doing this in my free time whenever I have the energies. Rust hates me.
You know what? It's actually not that bad once you know how to accept its
quirks (a.k.a. Stockholm's Syndrome).
I took all the learnings from last year:
- Always use tests before debugging the main problem statement
- Use nom to parse input unless it's very simple
- Iterators are your friends, even though it feels like they want you dead.
- About Iterators: use itertools, for your own sanity
I finished it! It was an uphill battle, but towards the end it became easier and easier.
Also, you might want to build everything with cargo build -r to check the
actual speed of the solutions. As an example solution to day 23 went from
6s 393ms 612µs and 9s 564ms 869µs in debug mode to 593ms 817µs and
678ms 579µs in release mode.
