These are my solutions to Advent of Code, written in Python 3.
There are many possible solutions for each day in AoC, and the solutions here are by no means the best way of solving the puzzles as they were written with the aim of solving each puzzle quickly.
Each script reads its input from input.txt placed in the working directory. The input for each day can be found on the Advent of Code website, for example the input for 2020 day 1 is located at https://adventofcode.com/2020/day/1/input.
