Now, let’s complete our code skeleton and write a circular queue. We want both front and rear to reset back to position 0 if the end of the queue has been reached (assuming the queue isn’t full). To tackle this problem, we need to make the queue circular. If you guessed that the queue will report back as being full, you are correct! To explain why we should create a circular queue, we’ll first explain the problem we’ll encounter if we’re just creating a linear queue.Īssuming you have a queue that can contain a total of five elements, the following operations are performed on the queue:Īfter those operations have been executed, the queue will look like this:Īs you see, there are 2 available spots in the queue, index 0 and 1.īut, if the queue isn’t circular, what will happen if we try to enqueue the number 6? We want our inner array to act as a ring buffer, which means that if either front or rear reach the last position of the array, we’ll reconnect it back to the start of the array. If you read the class comments, you might have noticed that two new terms have been introduced: Ring Buffer and Circular Queue.

* True if queue is full (size = arr.length), false otherwise. * True if queue is empty (size = 0), false otherwise. * Removing the front element from the queue. * The inner array acts as a Ring Buffer, which makes this a circular queue. We’ll also make our class generic, avoiding the general examples where you can only insert native int “objects” into the Queue.Ī code skeleton for our queue is presented out below. array : An inner array, containing the actual items in the queue.size : The current size of the queue (number of items).rear : The current position of the rear element.front : The current position of the front element.We’ll also need some private variables, both for keeping track of positions in the queue, and an inner array for the actual queue: isEmpty() : True if the queue is empty.size() : Returning the number of items in the queue.rear() : The rear method returns the item at the end of the queue, the most recently inserted item.Īpart from these four basic operations, we’ll also certainly benefit from some helper methods:.front() : The front method returns the item at the front of the queue (the next one to be removed when calling the dequeue method).dequeue() : The dequeue method removes the least recently inserted item from the queue.enqueue() : The enqueue method add an item to the queue.There are four basic operations that a queue should support: The one who has been waiting the longest should be expedited first. If you ever get confused, just compare the data structure to a line at the grocery store. In other words, " In a queue data structure, we remove the least recently inserted item." Unlike stacks, which follow the LIFO principle (Last In, First Out), a queue follows the FIFO principle (First In, First Out). The workings of the queue are very intuitive and easy to understand, as it works just as a regular queue (i.e. Our product offerings include millions of PowerPoint templates, diagrams, animated 3D characters and more.Today, I’ll cover the queue, which is a linear data structure. is brought to you by CrystalGraphics, the award-winning developer and market-leading publisher of rich-media enhancement products for presentations.
