Question#3.Write a Python program to reverse a stack using recursion. Problem Solution Hints: 1. Create a class Stack with instance variable items initialized to an empty list. 2. Define methods push, pop, is_empty and display inside the class Stack. 3. The method push appends data to items. 4. The method pop pops the first element in items. 5. The method is_empty returns True only if items is empty. 6. The method display prints the elements of the stack from top to bottom. 7. Define function insert_at_bottom which takes a stack and a data item as arguments. 8. The function insert_at_bottom adds the data item to the bottom of the stack using recursion. 9. Define function reverse_stack which takes a stack as argument. 10. The function reverse_stack reverses the stack using recursion. 11. Create an instance of Stack, push data to it and reverse the stack.
