#### My solutions to the [2020](https://adventofcode.com/2020) and [2021](https://adventofcode.com/2021) [advent of code](https://adventofcode.com).

#### My own rules :
 - **C** : Only *standard* libraries (for example, no external sort).
 - **bash**: Pure bash only: No external commands allowed (grep, sed, etc...).

#### Done 2020 (both C and bash, Cobol for day 1) :
 -  Day  1:     Bash, C, and Cobol
 -  Days 2-18:  Bash and C
 -  Days 19-22: Bash

#### Done 2021 (probably C only) :
 -  Day  1-22, 24: C
