gifski VS adventofcode

You can do that with ffmpeg, but the output isn't ideal

I'd use gifski: https://gif.ski/

If image quality is more important than size then give Gifski a try. No idea how it's on win but on a mac it's my default GIF solution.

To make a legitimate high quality GIF, you can try Gifski. YMMV, I haven't tried using it yet but that's what some of the people at highqualitygifs say they use to make actual GIFs.

To convert only - https://gif.ski

gifski does a great job at being relatively simple, while handling quality stuff for you.

gifski --fps 10 --width 320 -o anim.gif video.mp4

Part one went fairly fast, but spent quite some time on getting part two right. I settled on the approach of just iterating over the grid and using a boolean to see if I had to count elements or not. However, I had some issues figuring out when to swap, this post by /u/rogual helped me figure it out. After that I lost quite some time on an error that only occurred with my input, not with the example input. It turned out that my loop (which I take form my p1 solution) didn't include the start node, which caused all sorts of counting issues.
