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.

Today was way easier than the past week which is great, because I can relax a bit. I have rushed the code, so its not the greatest, but its here, in Javascript, if you want to see!

Today was insane for me. Basically spent like 10 hours working on it, but I started from scratch in the last hour and got both parts. I made very stupid mistakes such as reversing the values when reading them or writing a 2 instead of a 3. I am tired, but we are almost at the end! Part1 and part2 in Javascript.

Part1 and part2 in Javascript. Beware, code is ugly, didnt have time to clean it up and it also runs in like 3 minutes... :(

Today was very enjoyable, albeit a bit easier than expected after what was yesterday, haha. Part1 and part2 in Javascript

I think today was very difficult because of the way the problem was layed out. Most of what you need to do for part2 was explained in part1 for no reason and the example werent exhaustive. I tried doing it with sets, then I also tried bruteforcing it and in the end I ended up doing a more manual approach which is very ugly but I am too tired to refactor rigth now. Part1 and part2 in Javascript.
What are some alternatives?
