Busy day today, going back to sleep zzZZZ. Clean solution and walkthrough here later today (hopefully).

I am stuck!
If you're using Python, you can check this guy walkthroughs, he's good at explaining things and uses many Python's features to write clean code. I'd suggest to try tackle a problem on your own, and whether you manage to get a solution or not, read his walkthrough, and re-implement a solution using his ideas. This is what I did two years ago and it was a big help for me, I was more and more able to come up with solutions without looking at what he did. I still check what he does today, but I always solve the problem on my own first now.

All years, all days, everything in Haskell
I've done every year in Haskell (2015 2016 2017 2018 2019 2020 2021), and so have several other people such as /u/glguy. I don't see if /u/mstksg has anything published for 2015 but they've done 2016 2017 2018 2019 2020 2021 along with some pretty good writeups, I recommend checking those out.

Jetbrains looks like it's about to release Compose ui for ios, and web!
I ran my own benchmarks for a whole ton of code at https://github.com/ephemient/aoc2021 on both Linux x64 and macos x64, and ended up disabling Kotlin/Native because it was varying between 10x and 100x slower than Kotlin/JVM, eventually timing out on CI. The generated code may be reasonable thanks to LLVM, but the runtime certainly is not.

Took a while for me to get around to completing this in Kotlin, Python, and Rust as well, since I was working on optimizing other solutions, but I finally made it.

So I switched tacks and implemented this in Kotlin, where mutation is easier. First version was brute-force with duplicate state avoidance (checked before the state explosion at every input), which worked quickly enough for part 1, but ran into OOMs for part 2. Once I replaced the HashSet with a custom LruSet (and later a simpler CacheSet which simply overwrites on hash collisions) it ran part 2 in a few minutes. I then ported this into Haskell.

Kotlin, Python, and Rust solutions are the same solution but much uglier.

I'm doing the same cached recursion in Kotlin, Python, and Rust.
