How to print n times using recursion

So here we have used recursion The names which is before function will print FIFO & vice versa

func printNTimes(i: Int, n: Int) {
    if i > n {
        print("invalid,", i)
        return
    }
    print("Before-->", i)
    printNTimes(i: i+1, n: n)
    print("After-->", i)
}
print("Printing...")
printNTimes(i: 1, n: 5)
// It will print
Printing...
Before--> 1
Before--> 2
Before--> 3
Before--> 4
Before--> 5
invalid, 6
After--> 5
After--> 4
After--> 3
After--> 2
After--> 1
