Question:

Swift 5 allows to write functions (methods) with parameters. Examine the following s function:

func s (for x : Int) -> Int {
return x <= 1 ? 1 : x * s (for : x - 2)
}

How do you call it to calculate s of 4 and store it in an immutable variable a? What is the value stored in a?

Options

let a = s (4) // 24 is stored in a
let a = s (x: 4) // 12 is stored in a
let a = s (for: 4) // 8 is stored in a
let a = s (_: 4) // 16 is stored in a
There is an error in function square because you may not define for: as a parameter. You need to put _ instead of it.
