3. (5 points) Write a function n2top that receives and passes back an STL stack of integers, a stack, and receives an integer n. This function moves the nh element (counting from the top, which is element 1) of the stack to the top of the stack. For example, if an integer stack s has the elements: (top) 3 4 17 5 8, then after the call n2top (s, 4), the stack will have elements: (top) 5 3 4 178. You may use only additional (local) stack(s) and individual variables to solve this problem. (L.e., use other data structures is not allowed.)
