Advent Of Code 2021 Solutions

Here are my solutions for the Advent of Code Advent of Code. Implemented with Java 17 and Junit 5.

This december I developed a 2D-Matrix, which I used for multiple days, since I am planning to use this tool for other puzzles too, I moved the implementation to a own repository.
