Starting the 2015 Advent of Code challenge in GO

I discovered the advent of code in 2021, and did it in bash for the challenge. But since I started learning GO, I decided to code the previous AoC years in GO as a mean to practice it. So, although my bash code can be useful to see some tricks of a seasoned bash programmer, these GO solutions must be considered as "student code".

So I started coding the 2015 year of AoC in GO, available on my GitHub: advent-of-code-my-solutions/go/2015

The code is in GO, with some housekeeping scripts in bash.
