Advent of code in Rust - solving day 6/2021 (Twitch Live 2022-02-14)
4In this episode, we completed day 6 of Advent of Code y2021 using Rust!
Today's challenge was all about simulating fishes breeding other fishes over time and figuring out how many fishes in total would be present after a certain amount of iterations.
We did solve this challenge in an efficient way by realising that 1 fish could be in 1 of 9 possible configurations at a moment in time and count how many fish would exist in each possible configuration. This way we kept the state small even for trillions of fishes after a few hundred turns.
During the stream we did some refactoring to make the code simpler and faster.
If you have any suggestion, we'd love to hear it, so please leave a comment or a create a PR!
