Advent of Code 2021 - Day 9

In this video series, I try to challenge myself with the Advent of Code trials. Each solution will be published to Github, and I hope you will learn something from my coding mistakes and perhaps send some code my way on how you have done these challenges. I know by reading code, so this is such an exciting thing for me.

I liked today's puzzle; I've always liked recursion.

I solved it in a similar way to you, but I encapsulated the data a little differently. After I got my version working I realized I could have simplified my data structure a bit, but it's not worth optimizing now :)

My implementation did do a "normal" sort and then take the last three elements :) I knew there had to be a way to sort in reverse order but I didn't know the syntax. After watching your video I switched mine to sort reverse, and then I can use the first three which is a little cleaner looking.
