The only problem is if there is an odd number of repeated numbers then this won't work.

The gotcha with this is if you get a negative number.

I don't think Rust is a GC language.

GO Language Translation Added :D

I made the same mistake, I thought it meant they could play at least once and checked for playing and rejected if they did not play with every other player.

What does it mean by "Must reject an unknown player: True should equal False"

Do the playeres have to be sequential from "A" to "Z" or is there characters other than alpha tested for and those should be rejected?

haha, no worries, just repond here or msg me if people complain.
I am fairly decent at Fortran, so it shold work with out problems.

Thanks for the approval.

I agree, some of the Kata's are really easy in some languages and rediculously hard in other langauages.
It is a shame that kata ranks can be language dependent.

No problem at all, that should work.

No problem, how does that work? Do I just check back here in case there is discourse or is there some sort of automated email?
I am realitively new at codewars.

At some point I will try and throw in a Fortran version that will be simlar to the Go one.

The problem is the it passes a completed sudoku puzzle that the code must determine if it is valid or not. Random tests would just be reported as a fail every time, which would make the whole program mute. Plus Fortran95 does not include great random number generators (later extensions have bewtter ones).

I could add something that it randomly picks a subset of the pre-defined arrays.
I am a bit time limited, I just saw there is little Fortran suport on here, so I am trying to help out (I spend 80% of my work load writing Fortran 2008 code)
