Advent of Code 2021

Christmas is in danger, and Santa Claus needs your help to save it! Luckily for us, we can save Christmas with programming.

What is the Advent of Code?

The Advent of Code is an advent calendar, but with programming exercises as gifts. Each day, a new task will open up, which you can solve. The problems can be part of different fields of computer science, but they are still doable even for novice programmers. So even if you just started programming, or if you are an experienced veteran programmer, there is something to enjoy for everyone. More information and previous editions can be found at their website:
