What are the different types of queue structures?

There are several types of queue structures, including linear queues, circular queues, priority queues, and double-ended queues. Would you like to know more about any specific type?

Can you explain linear queues?

Sure! A linear queue is a data structure that follows a First In First Out (FIFO) principle, where the first element added is the first one to be removed. It has a fixed size and can be implemented using arrays or linked lists.

What about circular queues?

A circular queue is similar to a linear queue but connects the last position back to the first position, making it circular. This allows for efficient use of space, as it can reuse empty slots created by dequeued elements.

What is a priority queue?

A priority queue is a 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.

Can you give me an example of a real-world application of queues?

Certainly! Queues are commonly used in scenarios like print job management, where print jobs are processed in the order they are received, or in customer service systems, where customers are served based on their arrival time.
