Java (nothing special, simple implementation of the rules, I have only posted to fit for the rules here)

Java, the code is still a mess, but if you need some tips, it might help.

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.
What are some alternatives?
When comparing AlgorithmProblems and advent-of-code-2021 you can also consider the following projects:
competitive_programming - My solutions to programming contest problems from different sources (UVa, TopCoder, Live Archive, SPOJ, etc).
adventofcode
Advent-Of-Code
advent-of-code - My solutions for Advent of Code
advent-of-code - My Advent of Code submissions. For 2021 and before, these are the original code I used, without any modifications after-the-fact. As such, they are probably not as efficient or short as they should be, because I want a working solution faster, not a better solution. For 2022 and after, these are the solutions uploaded to my YouTube channel.
