My solutions for Advent of Code.
Solutions are in:
- ⭐ I was able to write a straightforward solution without any problems
- ⭐⭐ I ran into a few hurdles or bugs, but it eventually came together pretty smoothly
- ⭐⭐⭐ I needed to do some research to figure out how to do this one, or it took me many abortive tries to figure out a working method
- ⭐⭐⭐⭐ I couldn't figure this one out without seeing someone else discuss how they solved it
- ⭐⭐⭐⭐⭐ I couldn't figure this one out without seeing someone else's code
♥️ Really annoying; the problem statement was confusing, or the solution didn't feel worth all the effort, or Part 2 was unsolvable without knowing obscure theory♥️ ♥️ It was okay, I guess (usually because there's more parsing than solving)♥️ ♥️ ♥️ An average Advent of Code problem; not bad but not fantastic either♥️ ♥️ ♥️ ♥️ Fun and interesting to work through; I spent more time than average on tweaking and improving the solution because I was enjoying myself♥️ ♥️ ♥️ ♥️ ♥️ My favorite one of the year; it's the kind of problem I enjoy solving and the solution was elegant or interesting
