What are the differences between a circular queue and a linear queue?

What are the differences between a circular queue and a linear queue?

A linear queue is a straightforward data structure where elements are added at the back and removed from the front. In contrast, a circular queue connects the end of the queue back to the front, allowing for efficient use of space.

Can you explain how the circular queue works in more detail?

Sure! In a circular queue, when the end of the queue is reached, the next element is added at the front if there is space. This prevents the queue from becoming full even if there are empty spaces at the front.

What are the advantages of using a circular queue?

Circular queues are more efficient in terms of space utilization and can help avoid the 'queue full' condition when there are empty slots available.

Are there any real-world applications of circular queues?

Yes, circular queues are commonly used in scenarios like CPU scheduling, buffering, and managing resources in operating systems.
