If you are using custom Coord objects, you could consider going in and making a map of coord to value. Saves a bunch of boundaries checks, as you can see in zebalu's solution (another comment in thread) https://github.com/zebalu/advent-of-code-2021/blob/master/src/main/java/io/github/zebalu/aoc2021/Day09.java

Java 17, could be shorter, but I find this more readable (Gauss has helped a lot.)

Java 17, if you are looking for one. (However, it is not really a Java community...) I was really lost in diagonals, and it is not an "elegant" or less then 100 bytes of code solution, but I hope it is readable, if you are lost...

Hi! Nothing special, I might refactor later (since it is very rushed together), but Java 17, if you are interested.

[2023 Day 5] Exlplanation Like I'm 5
In the spirit of the Day 5 ALLEZ CUISINE! challenge to ELI5 (Explain Like I'm Five), here's a tasty explanation of how my algorithm works using only a large bucket of Red Vines and a knife. It says to use lined paper, but if you try this at home consider aligning things on a cutting board.

Bonus solution in Go (golang) because I was confused about why my Elixir solution didn't work and decided to implement from scratch in case I'd done something dumb. The Go one also got the wrong answer, but took less than 100ms instead of a minute, so I could try out lots of tweaks that didn't change the answer.

I spent time this afternoon sprucing up my helpers for the iex REPL. I spent a bunch of time poking at things in IEx the last couple days and wanted to make sure I would minimize keystrokes if I needed to debug things on my phone while drunk. Turns out Thursday night > Friday night > Saturday night in terms of difficulty, so all those macros have so far saved me zero seconds :-)
