WebTo insert values in a circular queue, we have to check the following conditions. If FRONT = 0 and REAR = MAX - 1 , then the circular queue is full. If REAR != MAX - 1, then REAR can be increased. If FRONT != 0 and REAR = MAX - 1, then it means queue is not full. Algorithm to insert an element in a Circular queue WebJun 23, 2024 · An overflow will occur when we try to insert an element into a queue that is already full. When REAR = MAX – 1, where MAX is the size of the queue, we have an overflow condition. Note that we have written MAX – 1 because the index starts from 0. Similarly, before deleting an element from a queue, we must check for underflow …
