16: Implement stack using linked list:
Let's give it a try! You have a linked list and you have to implement the functionalities push and pop of stack using this given linked list. Your task is to use the class as shown in the comments in the code editor and complete the functions push() and pop() to implement a stack.
Example 1:
Input:
push(2)
push(3)
pop()
push(4)
pop()
Output: 3 4
Explanation:
push(2) the stack will be {2}
push(3) the stack will be {2 3}
pop() poped element will be 3,
the stack will be {2}
push(4) the stack will be {2 4}
pop() poped element will be 4
