Here's some info on Advent of Code 2020. It's basically a series of coding puzzles. There's a few spots in Advent of Code every year where I got stuck on syntax or confused by the... "verbose"... narrative, and had to use other posted solutions as a reference. I've tried to point those spots out in the code or commit messages, but I'm not perfect, and it's all for fun anyway.
Speaking of fun, this challenge is a blast, and it's all put together by volunteers. It's been a nice way to challenge yourself in December.
I don't normally have a ton of time to optimize, but I've tried to do the best I can with the time I set aside for doing these challenges. ๐
