split a stream in many

Question

I\'d like to know if there a elegant way to achieve something like that:

val l = Stream.from(1)

val parts = l.some_function(3)  //any number

parts.foreach(         


        

Answer 1

scala> (1 to 30 grouped 3).toList.transpose foreach println
List(1, 4, 7, 10, 13, 16, 19, 22, 25, 28)
List(2, 5, 8, 11, 14, 17, 20, 23, 26, 29)
List(3, 6, 9, 12, 15, 18, 21, 24, 27, 30)
