  • Types of data Structure in DSA

    Underflow Condition: When a stack is empty (i.e.
    TOP= -1) and we try to delete more element from it, then this condition is called underflow condition..

  • What is a real life example of a stack in data structure?

    The stack data structure is a linear data structure that accompanies a principle known as LIFO (Last In First Out) or FILO (First In Last Out).
    Real-life examples of a stack are a deck of cards, piles of books, piles of money, and many more..

What is stack data structure?

A Stack is a linear data structure in which the insertion of a new element and removal of an existing element takes place at the same end represented as the top of the stack

To learn about Stack Data Structure in detail, please refer to the Tutorial on Stack Data Structure

Why do we need Prefix and Postfix notations?

What is the minimum element of a stack data structure?

Your task is to complete all the functions, using stack data-Structure

Input: Stack: 18 19 29 15 16 Output: 15 Explanation: The minimum element of the stack is 15

Since this is a function problem, you don't need to take inputs

Which interview questions use stack data structure?

In this post, we have listed out commonly asked interview questions that use stack data structure: Design a stack that returns a minimum element without using an auxiliary stack Find all elements in an array that are greater than all elements to their right Find preorder traversal of a binary tree from its inorder and postorder sequence

You might be tempted to try to read all of the possible questions and memorize the solutions, but this is not feasible
The Treiber stack algorithm is a scalable lock-free stack utilizing the fine-grained concurrency primitive compare-and-swap.
It is believed that R.
Kent Treiber was the first to publish it in his 1986 article Systems Programming: Coping with Parallelism.
