Online lunch: Advent of Code

Join fellow FP enthusiasts in coding up a solution in your favorite functional language, or a new language you want to try out!

Advent of Code is a series of fun coding problems found at https://adventofcode.com. Despite being relatively simple, they immediately require you read and parse input, giving you a taste of how it is to write an actual program in the language instead of just writing the core logic.

There is no need to prepare any setup: there are easy-to-use web-based environments for most languages.

Even if you are completely new, there will be someone to team up with and learn from/together with!
