[Rust] Random tests sometimes generate an empty vector vec![] which doesn't match the Kata description saying that an empty matrix is represented by vec![vec![]]

In Go is the input supposed to be named "snaipMap" instead of "snailMap"?

C translation has confusing initial code which is NOT illustrating what the user should return

  // Return a heap allocated array, report the size in *outsz
  return (int *)(*outsz = 0);

Is it just me or the empty matrix solution in GO give some problem?

"should return empty array given an empty array" - why does this mean that the array is not empty, but the first element of an input array is an empty array? lang Go
[]int{} -- empty array
[][]int{{}} -- is NOT empty, but kata assumes it is, but the input itself is wrong: it is not 0x0 or 1x1, it is 1x0, but not NxN

Hi, my golang solution passes all tests except random ones. However, I checked with a size of 6x6, it works. Are there any problems with kata tests on golang?

It's a very good kata, but I find weird that a len 0 array gets represented as [ [ ] ] since that would make a 1 x 0 grid, yet the description clearly states that it's an n x n grid.

Yes, I know it says at the bottom how it's represented. It still makes no sense.

I had to make an additional if statement to my solution so it would pass the empty array case, if it was just [ ] (0 x 0) it would've passed without the need of an additional if, as my solution (and many others from what I've seen in other comments) works for all grids n x n, what the kata asks for.

I'm rating it as somewhat satisfied instead of very satisfied because of that. I'll rate it very satisfied if it get's changed.

Doing the NASM version

There is no explanation what the parameters actually are

In the starting source there is

  ; <-- [dword RAX] snail([qword RDI] outsz, ro [qword [dword RSI]] mx, RDX m, RCX n) -->

No explanation there, in the testcode or in the description.

I guess I will just have to experiment how it's supposed to be.

In the C-version, which I did solve, there's this comment.

  // the numbers of rows and cols are passed separately for historical reasons

Does it apply to the NASM version as well?

well, i feel like idiot to be honest i just can't get what exactly i have to do i mean i can't get what exactly the question is
