Advent of Code 2021

I just discovered the Advent of code coding challenge. It exists since 2015, and seems really interesting in that it is language-agnostic.

Each day a problem is described, with input files consisting of numeric values for the problem. You must submit the answer which is a number by whatever means you want.

I started to do the current 2021 challenge, in bash to force myself to code in a more modern style that pass shellcheck. And later, i will probably do the other years in Go to learn it.

I publish my solutions as I code them on my github.
