What is stack: A stack in data

A stack in data structure is a linear structure that follows the Last-In-First-Out (LIFO) principle, where the most recently added element is the first one to be removed. This fundamental concept is integral to various applications and algorithms, making it essential to understand how it operates. Stack is a linear data structure that follows the LIFO (Last In First Out) principle for inserting and deleting elements from it. In order to work with a stack , we have some fundamental operations that allow us to insert, remove, and access elements efficiently. These include: push () to insert an element into the stack top () Returns the top element of the stack . pop () to remove an element from the stack isEmpty () returns true if the stack is empty else false. size () returns the size of ... The Stack is an important topic that comes under the Computer Science family. And, when it comes to competitive examinations like GATE, you need to know every aspect of the Stack . This article will enlighten you with in-depth information about Stacks. We believe that the information contained in the notes for the CSE topics will help you understand this topic in a better way. What is a Stack Operations on Stack Push Pop Peek Representation of the Stack Application of the Stack Advantages of ... Learn what a stack is , how it works, and how to implement it using arrays or linked lists. A stack is a data structure that can hold many elements and follows the LIFO (Last In First Out) principle.
