What are the different types of queues in data structures?

There are several types of queues in data structures, including simple queues, circular queues, priority queues, and double-ended queues (deques). Would you like to know more about any specific type?

Can you explain what a priority queue is?

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

How does a circular queue differ from a simple queue?

In a circular queue, the last position is connected back to the first position, making it efficient in utilizing space. In a simple queue, once an element is dequeued, that space cannot be reused until the queue is reset.

What are some real-world applications of queues?

Queues are used in various real-world applications, such as managing tasks in print spooling, handling requests in web servers, and organizing processes in operating systems.
