How do you see the input ?

raise to the power, thanks

Thanks, resolved.

Kata has been unpublished. Thanks

Thank you. has been fixed

Thank you. Has been fixed.

I take nothing away from the kata nor do i under rate it. It was just a constructive suggestion.

maybe make it a bit more fun, by saying the method should return
the sum of squares of the sums of all rows.

like this for example : given 2D array { {1,2},
{5,4,1},
{5}
}
Then the method should return sum = (3²) + (10²) + (5²)

Come on man, you shouldn't have shown people the code. I mean one doesn't even need to THINK here.
Please make a new version of this problem.

don't understand the question. please make me understand.
sort the numbers " By name ... " ???

It must be returned in what order ? The order confuses me
