This should be part of the description:

Length of code must not exceed 5000 symbols. Do not hardcode answers.

my code is working but it taketimes. so i could just pass 17 tests that it's time out

• should not print to console

Yes. I can't pass the tests because two elements are in different positions in various tests.

This shouldn't pass, but it passes.

The reference code in the description is missing the JS version.

Python: The sorting requirement in the description and in the tests don't match.

As described, the example output gets the second and third rectangles wrong (the second has a width of 2, the third a width of 1; the latter should come first as it shares a top left corner with the second but has a smaller width)

[
  [(1, 1), (1, 2)], 
  [(2, 2), (2, 3)], 
  [(2, 2), (3, 2)] 
]

The tests expect the output to simply be sorted lexicographically, i.e. without any special key function at all. This matches the output described above.

The description should have this requirement removed for Python (don't know about Haskell tests).

It's a pretty interesting kata and unique, that's for sure. The problem is that the description is quite confusing. You should provide some details about how the function should work, that would be much easier to make some tests, that would prove that the implementation is wrong.

Also, in C# tests break, when I call function with null as a parameter, I think you should probably look into that, because the first parameters, that would come to my mind when testing using string as paarameter is string.Empty and null.

I think that BigInteger would be preferred, since the result is expected to be a number. The fact that its decimal form has some interesting pattern and it happens to be convenient to be processed as string is just an implementation detail.

Random tests are incorrect, my solution sometimes passes, and sometimes fails.
