Struggled the whole weekend. Resorted to tons of hints. Started with naive ideas thinking there's some "simple trick", given it's supposed to run no longer than 15 seconds on 10yr old hardware. Had a version that worked on example and didn't finish on real data. Turned out I wasn't patient enough.

I'm not going to even comment on how much time I've spent figuring out "perimeter checking" after initial failed attempt with set based approach which was _crawling_. It's still brute-force but at least it executes reasonably fast.

Not exactly the most efficient code (changing cave state in place would probably help 😅 - as it is, it takes ~3 seconds to compute for full input), but it works! I got a bit stuck when solving part 2 due to my dumb brain hardly coping with imperative logic. I've sorted it out though.

I think I'll wrap my AoC with this day, as it's taking too much of my time. For part 2, I've misunderstood the requirements and tried to make the solution work using bigints - the program was grinding CPU to no end. Only after I've glimpsed somebody mentioning figuring out modulo to solve it, I've finally finished it.

Tripped up on a lot of suff several times over due to my stupidity, but this last sneaky corner case of latter knot following earlier one moving >1 spot on both axes was ... just ... mean. The tail position counts for part 1 and all examples were correct without considering it.

I was _this_ close to throwing in the towel. I have played myself by trying to reuse the algorithm from the first part in the second one and bashing my dumb head against the wall trying to make it work. Finally I gave in and went with the "naive" approach.

I got totally lost when it came to passing by value vs by reference and arriving at this solution took, uh, some time. At this rate, I'm not sure I'll be able to carry on :blobcatnervous:
