#### My solutions to the [2019](https://adventofcode.com/2019), [2020](https://adventofcode.com/2020) and [2021](https://adventofcode.com/2021) [Advent of Code](https://adventofcode.com), in C and Bash.

#### My own rules :
 - **C** : Only *standard* libraries (for example, no external sort). However, I may use my *own* includes and libraries (started in 2021).
 - **bash**: Pure bash only: No external commands allowed (grep, sed, awk, etc...).
