From the last step it is clear that there are two alternating series of numbers. One in descending order and the other in ascending order. When we go through input to step I, we find that the largest number because the first and remaining numbers shift rightward. In the next step the smallest number becomes the second and the rest shift rightward. These two steps continue alternately untill the two alternate series are formed.This step cannot be determined.
