Solve day 10 part 2
I'm so fucking frustrated with this one. I was stuck for hours trying to sort the points by angle not realizing that (int)(angle(a) - angle(b)) would be 0 for all angles with differences smaller than 1. I also wanted to do the sort by atan2(-y, x) - π/2 intuitively to get "up" be zero, but I never got that to work.
