Coding challenges solved for Advent of Code.
To use the makefile for setting up the daily challenge, first: create a file called sessionid and add a single line with your session id - you can get this by inspecting the Advent of Code cookies in your browser (right-click -> Inspect -> Storage -> Cookies).
Run make files year=X day=Y to get the input for year X, day Y and create code files based on the template.
Using pre-commit hooks:
pip install black
pip install pre-commit
pre-commit install
