![]() ![]() Now let’s see how to implement these operations in Python. Returns the element at the front of the queue without removing it. Adjust front index to loop back to 0 when it reaches max capacity.Increment front index to advance the queue.Check if the queue is empty before removing.Removes the oldest element from the front of the queue. Adjust rear index to loop back to 0 when it reaches max capacity.Increment rear index and insert element.Check if the queue is full before inserting.The main operations supported by a circular queue are: EnqueueĪdds a new element to the rear of the queue. They have applications in real-time embedded systems, audio processing, and computer graphics. Elements are removed from the front of the queueĬircular queues are useful when you need to buffer incoming data or transfer elements between threads efficiently.New elements are added to the rear of the queue.The queue capacity is limited by the size of the underlying array.The rear and front of the queue are connected.Stores data elements in a circular fashion using a circular array.The key characteristics of circular queues: The circular queue follows FIFO - first-in-first-out - order when enqueueing and dequeueing elements. This makes circular queues more memory efficient as the memory is reused when elements are dequeued. Unlike a regular queue that ends when it reaches capacity, a circular queue connects the rear to the front to make use of the empty space when the queue is not full. ![]() We will cover the following topics: Table of ContentsĪ circular queue is a linear data structure that stores elements in a circular fashion. In this comprehensive guide, we will learn how to implement a circular queue in Python. This makes circular queues more memory efficient than traditional linear queues. It is a linear data structure that utilizes a circular memory layout to store data elements, allowing both ends of the queue to be used to insert and remove elements.
