But I only realized this once I saw that my first solution wont cut it

part1

No idea, but I've since made a more sensible input parser: https://github.com/AlexAegis/advent-of-code/blob/master/solutions/typescript/2022/11/src/parse.function.ts

Well, you probably are because that's how I implemented it, lol: https://github.com/AlexAegis/advent-of-code/blob/c6c55bb49838fd214c519b07ed60e1d67cbcc641/solutions/typescript/2021/16/model/packet.interface.ts

I've tried it a few times and solutions were surprisingly elegant! E.g., 2020-01-p2.

Figured I'd post my benches as well, see below. Everything done in Rust (link to source).

Here's my day 24 in Rust, using SIMD as usual :) (and offset coordinate encoding to make a SIMD-friendly 2-D cell grid)

Borrowed both ideas in my version :) On my input your version runs at 3ms, mine in 1.5ms, so it might be faster on some inputs (link). I initially started with something similar to yours but then figured why not use 512-bit ints, so that the notion of 'head' and 'tail' disappears as your head then stays at position 0 (so, e.g., to remove a card, you just right-shift the whole bigint). Also used a tiny bit of simd along the way.
