Advent of Code 2019: https://adventofcode.com/
i don't have anything better to do this month tbh, guess i can have some fun. everything there will be created using C++ (preferably C++14), on my Ubuntu 18.04 WSL (GCC 7.4.0). Makefiles included, in case you'd ever want to compile and run this.
also i will try to make unit tests.
