Day 10: Pipe Maze

Megathread guidelines

  • Keep top level comments as only solutions, if you want to say something other than a solution put it in a new post. (replies to comments can be whatever)
  • Code block support is not fully rolled out yet but likely will be in the middle of the event. Try to share solutions as both code blocks and using something such as https://topaz.github.io/paste/ , pastebin, or github (code blocks to future proof it for when 0.19 comes out and since code blocks currently function in some apps and some instances as well if they are running a 0.19 beta)

    I have zero idea how this functions correctly. I fear to touch it more than necessary or it would fall apart in a moment.
    I got second star after 8 hours (3 hours for part 1 + 4 hour break + 1 hour part 2), at that moment I’ve figured out how to mark edges of enclosed tiles. Then I just printed the maze and counted all in-between tiles manually. A bit later I’ve returned and fixed the code with an ugly regex hack, but atleast it works.

      I printed the loop using box drawing characters, zoomed out, took a screenshot, and used GIMP to separate the inside and outside, and count the number of inside tiles.
