To be honest - this is kinda silly. Who the hell does this sort of thing? Appropriate task for SQL or something, but not for C.

Thanks for letting us know, but that kind of report is not very useful. Please explain which kind of inputs would fail your solution and give concrete examples. Also state the language you are using.

The half-assed solution of mine works, which probably means that test cases are lame and doesn't cover all of the possible corner cases.

Translating it to C/C++ or NASM seems like a joke.

Holds true for C and NASM variants:

1. Test cases (before "attempt") have only square matrixes. The are two arguments, that describe matrix dimensions - "m" and "n". What is row len and what is col len?
2. In the test cases the matrix is sent to assert function as a one-dimensional array. Somewhere in that function that array is transformed to a matrix, which is sent to snail function. Too obscure.

Awful description. What does the sale field contains? What type is it?

damn that was hard

Absolutely loved it

Fun kata. It's a shame that next katas in the series are not translated to NASM yet.

I hate this.

I have got so good at my black crapcode magic, that I did this in the first try.
With the exception of the mistake of putting EOL at the last line.

hey, that's pretty good

It's cool but it's not 4 kyu, it's much easier :(

I'd love to have the tasks of the same difficulty on my job.
