Nim
Decided to go for a polygon approach for part 1 using the Shoelace formula to calculate the area. This meant part 2 only resulted in larger values, no additional computation.
Code runs in <1ms for part 1 and 2 combined
Shoelace formula
This would have been really useful to know about. I've committed to a certain level of wheel-reinvention for this event unless I get really stuck, but I'm sure it'll come up again in the future.
This was actually something I learned for my job, it was nice to be able to apply it here.
I like your commitment to wheel-reinvention, it can be a lot more fun than going for an existing or 'intended' approach.
Yep, I figure it's good exercise to make me think through the problems thoroughly.
