.

That was my expectation also.

Is there a way to paste screenshots here? I have one with the output of the test suite.

Hi,

This map is expecting 0, not 1. You must have lookeed at the wrong input/output

Could someone please explain why is the correct volume 1 in the below test (I got it as one of the random tests, Python translation):

14, 0, 0, 12, 12

-5, 14, 10, 9, 9

-5, 2, 7, 7, 14

1, 5, 11, 13, 10

9, 0, 1, 1, 7

Thanks in advance!

This is an issue very specific to your personal approach (see your comment below), not a general issue. You just need to rethink how you tackle the problem. Hint: The number of depth levels should be irrelevant.

I think it would be nice to add to description that big maps have hundreds of different height values. It would prevent warriors from going the wrong path.

Finally, B4B making a translation after centuries XD

JS translation

cheers

Replied with a new fork fixing the issue. Thanks!

I found one problem, commented in your translation discussion section!

Hello there!

Rust translation ready for review!
(It's pretty much a 1:1 copy of the Python test suite)

Okay this one was properly difficult and fun, kudos! I've got a half working solution, but I'll leave it for now, to return later when I've sharpened my tools and brain...

It's a height map. Think of the numbers as heights of square columns stacked next to each other. Water spreads across equally high columns and trickles down into onto lower columns.
Water flows in cardinal directions only, not diagonally. Hence the bottom right corner is not a leak.
6*4: There are 4 colums of height 0 surrounded on all sides by columns of height 6; 6-0 = 6 -> 4*6
4*8: Ther eare 4 columns of height 0 surrounded on all sides by columns of height 8; 8-0 = 8 -> 4*8.

You can think of it like this: if it rained evenly all over the heightmap, where would water fill and stay?
