Hi lemmy, You all probably kniw about https://adventofcode.com/

I would love to do that with some students of mine. Only thing is, I’m not very good at it, so I can’t always figure out what the underlyong principles are.

Is there a place where someone (website, blog, github, erc), much better than I, explains each puzzle, how it’s solved, which algorithm is used, what underlying principles you can learn from this?
