Question

What is the functionality of the following piece of Java code?
Assume: ‘a’ is a non empty array of integers, the Stack class creates an array of specified size and provides a top pointer indicating TOS(top of stack), push and pop have normal meaning.
public void some_function(int[] a)
{
 Stack S=new Stack(a.length);
 int[] b=new int[a.length];
 for(int i=0;i<a.length;i++)
 {
  S.push(a[i]);
 }
 for(int i=0;i<a.length;i++)
 {
  b[i]=(int)(S.pop());
 }
 System.out.println("output :");
 for(int i=0;i<b.length;i++)
 {
  System.out.println(b[i]);
 }
}

a.

print alternate elements of array

b.
