Hi,
welcome to my solutions to the challenges of Advent of Code 2021. I present my solutions as a short post for every daily challenge. If you do not know what is going on, please go ahead and check out https://adventofcode.com/. I will not go into detail about the problem for day one, since you can simply visit https://adventofcode.com/2021/day/1.
The goal for this year is to solve every puzzle.
