🎄🎄 Advent of Code 2020 Solutions (Java) 🎄🎄

Here are my Java solutions for the 2020 Advent of Code challenge. I’ll be attempting to solve every puzzle — but
don’t expect perfect or reliable code.

You can attempt these awesome puzzles for yourself at https://adventofcode.com/2020.

Technicalities

These solutions use Java 9, and make heavy use of the built-in Streams API.

The main method accepts 3 optional arguments: [day] [part] [version]. If no arguments are passed to the application,
then it will run all of the solutions and print them to the console.
