Question - How can elements be inserted in the circular queue?
Answer -
There are two cases in which items can be placed in a circular queue. They are as follows:
- When front != 0 and rear = max -1. This makes it possible as the queue will not be full, and new elements can be inserted here.
- When rear != max -1. This ensures that the rear is incremented to the maximum allocation size, and values can be inserted easily to the rear end of the queue.
