1. Overview
A stack is a data structure that works according to the principle “last in, first out” (LIFO – Last In First Out). This means that the last element inserted into the stack will be the first one to be removed. Stack as a data structure can be implemented in a special linear data structure called a List. The main operations that can be performed on a stack are push and pop. Push inserts an element into the top of the stack, while pop removes an element from the top of the stack.
2. How LIFO works – Last In First Out work
LIFO is an abbreviation for last in, first out. It is a method of handling data structures where the first element processed is the last one placed in the structure. LIFO is used in accounting to manage inventory and often results in lower taxes because newer, more expensive items are taxed less than older ones.
3. Stack in JavaScript
A stack is a data structure that holds a list of elements. A stack works based on the LIFO principle, which stands for Last In First Out. This principle dictates that the element that is added at last is accessed first. In other words, a stack is a last-in-first-out (LIFO) data structure. It has three primitive operations: Push, Pop, and Peek.
Push adds an element to the stack,
Pop removes an element from the stack,
Peek returns the top element of the stack without removing it.
4. Different Stack operations in JavaScript
A stack is a data structure that implements two operations – add an element and remove an element. Both operations take place from the top of the stack. The stack can be realized using different data structures such as arrays, linked lists, etc.
5. Data structure Stack real life examples
Data structure stack can be used for Expression Evaluation and Conversion, and in many areas like word processor undo and redo actions.
A stack is a data structure that stores items in a Last In First Out (LIFO) manner. An example of a stack in real life is a deck of cards. The card at the bottom of the deck is the first one to be dealt, while the card at the top of the deck is the last one to be dealt. Other examples of stacks include a pile of books, a stack of dinner plates, and a queue of people waiting to buy tickets.
6. Conclusion
A stack is a basic data structure that can be used to store and manage data in a required manner.
It is easy to implement as a program and uses the LIFO approach, which means that only the last element added can be accessed.
Data structures play a significant role in arranging data in a specific format or order within an application, and stack is one of the most popular and widely known data structures.
