Advent of Code Problem 19b - Nondeterministic parsing with Yoctoparsec
Last year I took some time to solve the 2020 Advent of Code problems. Most of the problems were easy - the second part of each problem usually being slightly harder. I needed a couple of hints to get me through a couple of the problems when I felt I was missing a piece of the puzzle but I only did that twice - for problems 13b and 22b. However, for problem 19b I refused to cheat and pushed through until I got to the solution.
