In the words of its creator Eric Wastl:
"Advent of Code is an Advent calendar of small programming puzzles for a variety of skill sets and skill levels that can be solved in any programming language you like. People use them as a speed contest, interview prep, company training, university coursework, practice problems, or to challenge each other."
Keeping it simple this year—no YouTube videos, and I won't be recording the time it took me to complete each answer, so I'll just post my official time and rank for each puzzle below. on_the_day solutions are exactly the code I had when I submitted my answer (within 24 hours of the question being released at 5am GMT each day), and tidied_up solutions are the code after making edits to optimise and/or prettify it.
