How do you rotate (circular shift) of a Scala collection

Question

I can do this quite easily, and cleanly, using a for loop. For instance, if I wanted to traverse a Seq from every element back to itself I would do the

Answer 1

This is a simple piece of code

  object tesing_it extends App 
{
val one = ArrayBuffer(1,2,3,4,5,6)
val  i = 2  //the number of index you want to move



 for(z<-0 to i){
   val y = 0
   var x =  one += one(y)
   x = x -= x(y)
   println("for seq after process " +z +" " + x)
  }


println(one)

}

Result:

for seq after process 0 ArrayBuffer(2, 3, 4, 5, 6, 1)

for seq after process 1 ArrayBuffer(3, 4, 5, 6, 1, 2)

for seq after process 2 ArrayBuffer(4, 5, 6, 1, 2, 3)

ArrayBuffer(4, 5, 6, 1, 2, 3)
