What is a circular queue and how can I visualize it?
A circular queue is a linear data structure that follows the FIFO principle but connects the end back to the front. You can visualize it as a circular arrangement of elements.
Can you show me a diagram of a circular queue?
Sure! Imagine a circle where the first element connects to the last element. Each position in the circle represents an element in the queue.
How does the enqueue and dequeue operation work in a circular queue?
In a circular queue, when you enqueue, you add an element at the rear and move the rear pointer. For dequeue, you remove an element from the front and move the front pointer.
What are the advantages of using a circular queue?
Circular queues utilize space efficiently and avoid the wastage of space that occurs in linear queues when elements are dequeued.
