STACK AND OPERATIONS

  STACK AND OPERATIONS Stack: Stack is a linear data structure that follows LIFO (Last In First Out) Principle , so the last element inserted is the first to be popped out. In this article, we will cover all the basics of Stack, Operations on Stack, its implementation, advantages, disadvantages which will help you solve all the problems based on Stack. Operations: Push: This operation adds an element to the top of the stack. When you push an element onto a stack, it becomes the new top element. Pop: This operation removes the top element from the stack. When you pop an element from a stack, it removes the top element and returns it.
