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)

Rust Solution

Used Shoelace Algorithm to get the interior area and then Pick's Theorem to get the number of interior points based on the area and the points along the boundary loop.

It's so humbling when you've hammered out a solution and then realise you've been paddling around in waters that have already been mapped out by earlier explorers!
