In a queue, elements are added at one end, known as the “rear” or “enqueue” operation, and removed from the other end, known as the “front” or “dequeue” operation. This ensures that the oldest elements are processed before the newer ones. Get ready for high-paying programming jo...
Unlike an array, it is not possible to randomly access elements in a queue. It is strictly a buffer that provides you the ability to enqueue (add/insert) and dequeue (subtract/remove) elements. The only way to view all the elements in a queue is to dequeue them one by one. You ...

A double-ended queue is also known as a deque or a dequeue (pronounced “deck”). Techopedia Explains Double-Ended Queue A deque allows the programmer to freely interact with the list of objects. While a deque seems to have all the features of stacks and normal queues, it lacks some of...

The way queue data structures operate is very straightforward: Enqueue: Insert a data element to a queue’s rear. Dequeue: Remove the element from the queue’s head. Peek or Front: Check the element at the head of the queue without removing it. Rear: Check the element at the tail ...

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 in data structures.
