Challenges hosted on the Cave Of Linguists Discord server from 01/12/2020 to 25/12/2020. Aimed at beginner/intermediate programmers.
Still available at: https://regyxxer.xyz/coladvent
I have no affiliation with the offical advent of code, hosted over at https://adventofcode.com
This was hosted on a website, through Github Pages.
To host this yourself, Be sure to replace the submission links for every challenge! I've updated them in index.md and template.md, but the other challenges link to an old Google Forms page that is not in use anymore.
