Drawbacks of Queue (Linear Queue)

  • With the array implementation of Queue, the element can be deleted logically only by moving Front = Front + 1.

CIRCULAR QUEUE

In Circular Queue, the insertion of a new element is performed at the very first location of the queue if the last location of the queue is full, in which the first element comes just after the last element.
