* Spoiled solve day 13 part 2June McEnroe2020-12-13
| | | | | | I think I might've been close to coming up with this at some point but everyone was acting like it was impossible without knowing "Chinese Remainder Theorem" and I just got pissed off.

| | | | | In classic fashion, I typo'd an x as a y and failed to catch it until reading over the code for the 5th time.

| | | | | Much tougher than part 1. I got tripped up on using an int where I needed a long again. That number is huge!

| | | | | | The read builtin returning 1 for EOF when the last line doesn't end with a newline tripped me up. Only a problem because I like to just copy the input and use pbpaste, I guess.

| | | | | | | | 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.

| | | | | Yikes, I had gotten annoyed at this on day 7 because I didn't see what was wrong. Turns out I was just missing amp[0].in = 0.

| | | | | | | Dang, I got screwed up by normalizing the lines in place rather than just for the intersection function. When it came to calculating the length of the final segment to the intersection, the "last" point was sometimes the wrong end.
