Advent of Code 2020 - Day 25
In the spirit of the holidays (and programming), I’ll be posting my solutions to the Advent of Code 2020 puzzles here, at least one day after they’re posted (no spoilers!). I’ll be implementing the solutions in R because, well, that’s what I like! What I won’t be doing is posting any of the actual answers, just the reasoning behind them. Also, as a general convention, whenever the puzzle has downloadable input, I’m saving it in a file named input.
