Threading While Loops into Closures in Swift

Closer While Loops swift

// multiplies by adding using a while loop within a closure
var MulbyAdding = {(x:Int, y:Int) -> Int in var add = 0; var count = 0; while count < y {
    add += x
    count += 1
    }; return add
}
// A Power closure that uses MulbyAdding and a while loop
var PowerbyMul = {(x:Int, y:Int) -> Int in var Pow = x; var count = 0; while count < y {
    Pow *= x; count += 1
    }; return Pow
}
