Apr 7, 2025 · A Queue Data Structure is a fundamental concept in computer science used for storing and managing data in a specific order. It follows the principle of "First in, First out" (FIFO), where the first element added to the queue is the first one to be removed.

Basic Operations of Queue. A queue is an object (an abstract data structure - ADT) that allows the following operations: Enqueue: Add an element to the end of the queue; Dequeue: Remove an element from the front of the queue; IsEmpty: Check if the queue is …

Jul 9, 2024 · This article covers the implementation of queue using data structures and modules from Python library. Python Queue can be implemented by the following ways: list; collections.deque; queue.Queue; Implementation using list. List is a Python’s built-in data structure that can be used as a queue.

What is a Queue? A queue is a linear data structure where elements are stored in the FIFO (First In First Out) principle where the first element inserted would be the first element to be accessed. A queue is an Abstract Data Type (ADT) similar to stack, the thing that makes queue different from stack is that a queue is open at both its ends.

Basic operations we can do on a queue are: Enqueue: Adds a new element to the queue. Dequeue: Removes and returns the first (front) element from the queue. Peek: Returns the first element in the queue. isEmpty: Checks if the queue is …

Jan 15, 2025 · To implement queues in data structures, arrays, and linked lists are commonly used, with array queues in data structures being one of the fundamental implementations. In this DSA tutorial, we will examine the queue data structure in detail, including its features, workings, implementation, etc.

Mar 24, 2023 · How to Create a Queue in Data Structure? The queue can be created using below 2 data structures.: 1. Using Array. In this representation, an array is declared with N number of elements capacity and 2 indices FRONT and REAR are maintained. In the case of insertion and deletion of elements in the queue, indices are updated accordingly.
