Stack Algorithm in Data Structures - Learn about the Stack Algorithm in Data Structures, including its working principles, operations, and applications. Explore examples and implementation details.

Mar 6, 2025 · Stack is a linear data structure that follows LIFO (Last In First Out) Principle, the last element inserted is the first to be popped out. It means both insertion and deletion operations happen at one end only. LIFO (Last In First Out) Principle. Here are some real world examples of LIFO. Consider a stack of plates.

Nov 13, 2024 · In C, we can implement a stack using an array or a linked list. In this article, we will use the array data structure to store the stack elements and use a pointer to keep track of the topmost element of the stack. The stack will offer some basic operations like push, pop, peek, isEmpty, and isFull to the users.

Dec 16, 2013 · Make a class stack with a list as an attribute and three method Push(), PoP() and Display() to perform the relevant operations in addition to the __init__() method. The class should be able to handle the exception if data is tried to be popped from an empty stack

Mar 27, 2025 · The Java Collection framework provides a Stack class, which implements a Stack data structure. The class is based on the basic principle of LIFO (last-in-first-out). Besides the basic push and pop operations, the class also provides three more functions, such as empty, search, and peek.

Stacks can be used to implement undo mechanisms, to revert to previous states, to create algorithms for depth-first search in graphs, or for backtracking. Stacks are often mentioned together with Queues, which is a similar data structure described on the next page.

Apr 5, 2021 · There are two operation which can be performed on stack. 1). PUSH. 2). POP. 1). PUSH operation of Stack. PUSH operation of the stack is used to add an item to a stack at the top. We can perform Push operation only at the top of the stack. However, before inserting an item in the stack we must check stack should have some empty space.

In this tutorial, you will understand the working of Stack and it's implementations in Python, Java, C, and C++.

Algorithm to initialize a stack using array. TOP points to the top-most element of stack. 1) TOP: = 0; 2) Exit. Push operation is used to insert an element into stack. Algorithm to push an item into stack. 1) IF TOP = MAX then. Print “Stack is full”; Exit; 2) Otherwise. TOP: = TOP + 1; /*increment TOP*/ STACK (TOP):= ITEM; 3) End of IF.

Nov 8, 2015 · Write a C program to implement stack data structure using linked list with push and pop operation. In this post I will explain stack implementation using linked list in C language. In my previous post, I covered how to implement stack data structure using array in C language.
