| | | | | | | | | Is it cheating to implement the FORTRAN I approach[1] as preprocessing? Maybe. [1]: https://en.wikipedia.org/wiki/Operator-precedence_parser#Alternative_methods | ||

| | | | | | | There are <512 writes in the input data, and at most 9 bits floating. Doesn't really matter much, though. | ||

| | | | | | | | 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. | ||
