Question: In a circular queue, what happens when the rear pointer reaches the end of the array?

Options:

Correct Answer: It resets to the beginning of the array

Solution:

In a circular queue, when the rear pointer reaches the end of the array, it resets to the beginning of the array to utilize the available space.

In a circular queue, what happens when the rear pointer reaches the end of the array?

In a circular queue, what happens when the rear pointer reaches the end of the array?

Step 1: Understand that a circular queue is a data structure that uses a fixed-size array to store elements.
Step 2: Know that the queue has two pointers: the front pointer and the rear pointer.
Step 3: The rear pointer indicates where the next element will be added in the queue.
Step 4: When the rear pointer reaches the end of the array, it means there is no more space to add new elements at the end.
Step 5: Instead of stopping, the rear pointer resets to the beginning of the array (index 0) if there is available space there.
Step 6: This allows the circular queue to efficiently use the space in the array without needing to move elements around.

Circular Queue Behavior – In a circular queue, the rear pointer wraps around to the beginning of the array when it reaches the end, allowing for efficient use of space.
