Part 1 was straight forward path finding, just annoying to keep track of indexes. I need to take a break and think about part 2 https://i.rdrama.net/images/1702191758939138.webp

Kinda crazy to keep track of a max value when you can just find the length of the loop by traversing it once and divide by two

Thanks, that's a good trick. This is my first time doing coding puzzles so I'm suprised I'm keeping up tbh

I like seeing strange approaches to problems. It adds one more thing to the toolkit that might be needed later

It's simpler than path finding in that there is only ever one direction you can go, originally I thought I'd have to pull out A* and was relieved that it wasn't that kind of problem.

I think I went this way because you don't know the shape of S, but yeah, I could probably combine the neighbour finding and path building steps if I was smart about it

Part 2 (algo from SO) and cleaned up because doing it with flat arrays was stupid
