What are advanced queue structures and their applications?

What are advanced queue structures and how do they differ from basic queues?

Advanced queue structures include priority queues, circular queues, and double-ended queues. They differ from basic queues by allowing more complex operations and prioritization of elements.

Can you explain how a priority queue works?

A priority queue is a data structure where each element has a priority. Elements with higher priority are dequeued before those with lower priority, regardless of their order in the queue.

What are some real-world applications of advanced queue structures?

Advanced queue structures are used in various applications like task scheduling in operating systems, managing print jobs, and handling requests in web servers.

How do circular queues improve efficiency?

Circular queues improve efficiency by reusing empty spaces in the queue, allowing for better memory utilization and reducing the need for shifting elements.
