My solutions for the Advent of Code 2020 challenges.
You need to store your sessionId (found in the session cookie on adventofcode.com when logged in) in the config.json,
for the reader to fetch your input.
Or copy it by yourself and paste it in inputs/[DAY].txt,
where [DAY] is the day of the input you are copying in the format DD.
E.g.: inputs/01.txt if you copied the input for the day 1 challenge.
To test a specific day, just set the DAY constant in the index.js to one of the values of the days constant.
Just type npm start to run the code for the set day.
