🌲 Advent of Code 2020 🌲

Solutions for the Advent of Code 2020 puzzles, written in Javascript.

Every day two new puzzles are released, but you need to solve the first to unlock the second. Each puzzle grants a star, so the objective is to get all 50 stars. My aim is to code efficient solutions and comment them so that they can be easily understood.

Thanks Eric Wastl for organising this event!

Project structure

Every day has its own folder with the following files:

• input.js: the puzzles input, formatted in a suitable way to solve them
• puzzle1-solution.js: the solution to the first puzzle
• puzzle2-solution.js: the solution to the second puzzle
• README.md: the explanation of each solution

To run any solution, you can use Node:

# Runs the solution of the first puzzle of Day 1
node day1/puzzle1-solution
