Advent of Code is a popular yearly programming competition. It's an Advent calendar of small programming puzzles for a variety of skill sets and levels that can be solved in any programming language you like.

Puzzles are released daily throughout December. More than 150k people take part in this event. The toughest battle to solve each puzzle as soon as possible to become the best on the global leaderboard.

In my timezone, puzzles are released at 6 o'clock in the morning. Since I'm a night owl, the biggest challenge for me here is to get up so early. I, therefore, set a different goal instead.
