My solutions to Advent of Code 2019.
There is a folder for each day's problem, and they are intended to be standalone as much as
possible. The solution files have a main() method at the bottom which delegates to some helpers.
Solutions are written in Python 3. Some contain language features added in Python 3.8 😍 so may not run on earlier Python versions.
Non-trivial solutions have associated tests that can be run with pytest.
