Day 11 in Rust. Felt like this might be computationally intensive, and Rust can be so fast.
Went pretty well other than my Rust got a little rusty (pun partially intended) since I last wrote some:
- Started with Arrays but much easier to work with a Vec when you don't know size in advance.
- Little bits about remembering what to make mutable, when to use references, etc. No serious borrow-checker problems, other than just ... getting back used to it.
- No lifetime issues here, which definitely helped.
Definitely ran quickly -- didn't spend any time on performance because was totally unnecessary.
I used CLion 2021.3 (after updating), cargo init to set up the project, and no external dependencies.
