Uiua

A bit late getting to this, but happy with this solution, despite it being nothing more than just building/summing all paths. As usual, you can drop your own file onto that solution.

Man, your solution is so much cleaner than the hell I was trying (and failing) to coerce into doing what I wanted. Curse my inability to think bottom-up and array-oriented at the same time!

When I compare it to some other Uiua solutions on the Discord I feel like I'm still just banging rocks together.
