Scala version def f(n: Int) = println("Hello World\n" * n)
def f(n: Int) = println("Hello World\n" * n)
better to avoid materializing big strings:
def f(n: Int) = Stream.fill(n)("Hello World") foreach {println}
Is mine functional or rather lame?
def f(n : Int) : Unit = { println("Hello World"); if (n > 1) f(n-1) }
Hello World N Times
