We will study the data structure concept of dequeue or double ended queue in this article. Let’s first take a quick look at what a data structure is before we get started with the dequeue or double ended queue
A queue data structure is a fundamental concept in computer science, serving as a collection of elements with a specific order and set of operations. Queues follow the First-In-First-Out (FIFO) principle, meaning that the first element added is the first one to be removed. A queue is ak...

Queues are a fundamental concept in computer science and various industries, providing an effective means of managing and organizing tasks, requests, and processes. They offer benefits like fairness, efficiency, and improved customer experience. Whether in computing systems, real-time operations, customer...
What is the normal real-life application of queues? People wait in queues to await their chance to receive a service. Programming follows a similar concept.Let us look at some application of queue data structure in real-life applications :- ...
In computer science it works as a CPU scheduling in an operating system as well as in real life on railway reservation counter and at a ticket counter of multiplex. Each of this show that element moved from their respective position while deletion occur, but the concept of queue shows that ...
To retrieve an item from the Hashtable, you can index the Hashtable by the key, just like you would index an array by an ordinal value. The following short C# program demonstrates this concept. It adds a number of items to a Hashtable, associating a string key with each item. Then, ...
Queue is used in CPU Scheduling. Queue is used in Asynchronous processes. This article tried to discussQueue Data Structure. Hope this blog helps you understand the concept. To practice problems feel free to checkMYCODE | Competitive Programming....
ordering food in a restaurant. The queue data structure follows last in first out (LIFO) order for accessing elements. The element which was added first can only be accessed or deleted. In this article, we will study the underlying concept behind queue data structure and implement it in ...
In the above example, we used the queue concept and joined a mutable list interface to store and retrieve the data operations. Example #2 Code: class SecondExam { private val sizes = 8 private var arraqueues: IntArray = IntArray(this.sizes) ...
