Sort a given stack - Using Recursion | Algorithms

Objective: Given a stack of integers, write an algorithm to sort the stack using recursion. Example: Original Stack: [14, 9, 67, 91, 101, 25] Sorted Stack: [9, 14, 25, 67, 91, 101] Approach: In this solution, we need two recursive functions. sorting() and sortingUtil().
