Advent of Code 2022

This will be the best advented code ever! Trying to use test driven development and typed python.

Code auto-formatted with black

Things I learned

set()s are awesome to get unique elements from a list
set()s also allow you to find intersections and overlaps
need to tell VS Code to use setup.cfg for activated linters (see .vscode/settings.json)

TDD on top level is always worth it
adding tests for smaller steps creates very modular code..maybe too many functions, seem to lack cohesion because all functions are only used one time
beware of edge cases (day8: extreme values sitting on the edge of the map)
just because you think that two implementations do the same thing, does not mean they do (test them both)
using dict() or list() for instantiation is slower than using the literals {}, []
using typing.Dict/List was necessary pre Python 3.10 but now dict/list/tuple[] are preferred solutions without additional imports
a customized solution may be a lot faster than a generic one (day12)
