My personal solutions for Advent of Code 2020. I've attempted these in Python & C++.
All source code is located in the src/ directory; each day is self-contained (eg. for CMake) and solution source code is split by language as well.
The recap/ directory contains my "trip-report" of the experience. I describe the main concepts of each problem, what I found notable about a given day, what I struggled with, etc. In addition, I document other useful stuff I learnt (plus examples to reinforce concepts).
