Advanced 13.3: Advent of Code#

In December, you might like to try Advent of Code, an Advent calendar of small programming puzzles that can be solved in any programming language. The puzzles are released daily, and require only basic programming skills to solve. There are usually two parts to each puzzle, the first being easier than the second.
