These are my Solutions for Advent of Code 2021 (in Java), 2022 (in Java) and 2023 (in Python).
They are
a) not complete and (especially 2022, lol)
b) not commentated or written in an easily readable way and
c) probably not the best or even good.
(and the last days (16/17) of 2021 probably don't work properly, idk)
