What is the difference between a circular queue and a regular queue?

A regular queue follows a linear structure where elements are added at the back and removed from the front. In contrast, a circular queue connects the end 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 can be added at the front if there is space, effectively reusing the empty slots. 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?

The main advantages include better memory utilization and reduced waiting time for operations, as it minimizes the need for shifting elements.

Are there any disadvantages to using a circular queue?

Yes, one disadvantage is that it can be more complex to implement than a regular queue, especially in managing the front and rear pointers.
