[2022][Friendly Reminder] Don't commit your input files to Git
Caution: the method I used is not recommended. Use at your own risk, know what you're doing, and have plenty of backups, etc. That said, here are my notes.

Once I figured out how to elegantly move the tail using signum() in part 2 it became so much cleaner. Full code is on GitHub, but here's the core of it:

Group the fish by their timer, which can be anything from 0 to 8. The neat part is the rotate_left to decrease the timers of each group. Fish with timer 0 will automatically end up at timer 8, and so the only thing left to do is adding another copy with timer 6. Core function: rust fn multiply(timers: Vec, generations: usize) -> usize { // Index equals timer value, so index 0 contains the count of fish with timer 0 let mut counts_by_timer = vec![0usize; 9]; timers.into_iter().for_each(|f| { counts_by_timer[f] += 1; }); for _ in 0..generations { // A left rotation represents the timer (=index) decreasing by 1. // The fish with timer 0 will not only produce new fish with timer 8, // but also reset their timer to 6 let count_of_fish_with_timer_0 = counts_by_timer[0]; counts_by_timer.rotate_left(1); counts_by_timer[6] += count_of_fish_with_timer_0; // == counts_by_timer[8] } counts_by_timer.into_iter().sum() } Full code at Github

Swift. I tried to use GameplayKit's pathfinding, but I got fed up with it being in Objective-C and not working with subtypes properly. shortestPathSources is just an implementation of Dijkstra that works on matrices.

Swift. Algorithms had me covered for Part 2, but I had to make something for Part 1 that would allow for getting the elements of a Sequence based on sorted offsets, without having to start from the beginning each time.

I recommend SIMD2โit can save you a lot of reinventing the 2D wheel!

Swift. containsOnlyUniqueElements is not in the standard library; it relies on this Set initializer.

No, I edited my comment. I was wrong in thinking that there was a proper overload. The one I'm using is just from `extension Collection where Self.Element : Equatable` in the new _StringProcessing section for Regex. It gives the correct result, but it's not as fast as it could be.

Swift, using some helpers for `CaseIterable`.
