Detailed explanation-1: -A circular queue is the extended version of a regular queue where the last element is connected to the first element. Thus forming a circle-like structure. The circular queue solves the major limitation of the normal queue. In a normal queue, after a bit of insertion and deletion, there will be non-usable empty space.
Detailed explanation-2: -Easier for insertion-deletion: In the circular queue, elements can be inserted easily if there are vacant locations until it is not fully occupied, whereas in the case of a linear queue insertion is not possible once the rear reaches the last index even if there are empty locations present in the queue.
Detailed explanation-3: -Memory management: circular queue is used in memory management. Process Scheduling: A CPU uses a queue to schedule processes. Traffic Systems: Queues are also used in traffic systems.
Detailed explanation-4: -There are four different types of queues: Simple Queue. Circular Queue. Priority Queue.
