Hello,
I'm trying to go through the challenge. Anyway I'm not able to pass as the system has problems with my code while it apparently works as my playground does not have problems at all with my code. Please have a look and point , if possible what is not OK with my solution.
Regards.
/**
For this code challenge, let’s define a math operation as a function that
carries out some work on two integers and returns an integer as well. An
example is the function below, `differenceBetweenNumbers`, which takes two
integers and calculates the difference between the numbers. After calculating,
it returns the difference.
*/
func differenceBetweenNumbers(a: Int, b:Int) -> (Int) {
return a - b
}
// Enter your code below
func mathOperation (r: (c: Int, d: Int)->(Int), e: Int , f: Int) -> (Int) {
return r(c: e, d: f) as Int
}

Also, you don't have to cast the result to Int because the function already returns an Int.
func mathOperation (r: (Int,Int)->(Int), e: Int , f: Int) -> (Int) {
return r(e,f)
}
