Summary for those just joining us:
Advent of Code is an annual Christmas themed coding challenge that runs from December 1st until christmas. Each day the coding problems get progressively harder. We have a leaderboard and pretty good turnout, so feel free to hop in at any time and show your stuff!
Whether you have a single line monstrosity or a beautiful phone book sized stack of OOP code, you can export it in a nice little image for sharing at https://carbon.vercel.app

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

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
