"Advent of Code is an Advent calendar of small programming puzzles for a variety of skill sets and skill levels that can be solved in any programming language you like. People use them as a speed contest, interview prep, company training, university coursework, practice problems, or to challenge each other."
There are 25 puzzles, each puzzles contains 2 stars to unlock. I have been participating in the AoC event for 4 years, each year I try to improve for the previous experience and get further!
