No-Human Advent of Code 2021 (Github Copilot ONLY): Day 1-4

Hello everyone, I recently got access to Github Copilot, an AI coder who follows along helping you as you code.

Usually, the human coder will need to write some code to start it off, but I'm restricting myself to ONLY letting Copilot write fully functional code.

I will only do comments and variable names, and we'll be going as far as possible into the Advent. Happy Holidays everybody!
