in thread [OT] Swapping buffers in place.

Now we basically have a smaller array 4 5 6 1 2 3 and we want to swap 4 5 6 and 1 2 3. Hence, recursion.
(actually, in this particular example we still have 3 iterations left in the for loop. The function recurses if the size of the left part of the array is less then or equal to the right part)
