Advent of Code 2020
An attempt to solve each of the adventofcode.com 2020 puzzles in Python as they're released. The solutions carry the additional self-imposed restriction of not using any imports (with the exception of assistance to read each problem's input file).
If the code's here, that means the solution works, not necessarily that it's optimal, although optimization is still a goal.
Each solution can be run standalone, without dependencies, with python 3.6+.
