The enqueue Operation on a Circular Queue There are three scenarios which need to be considered, assuming that the queue is not full: If the queue is empty, then the value of the front and the rear variable will be -1 (i.e., the sentinel value), then both front and rear are set t...
There was one limitation in the array implementation ofQueue. If the rear reaches to the end position of the Queue then there might be possibility that some vacant spaces are left in the beginning which cannot be utilized. So, to overcome such limitations, the concept of the circular queue w...
If we want to insert another element G in to the above queue. Here FRONT=2 and REAR=6+1=7. But there is no space at the rear end. That is the does not have the location 7. The queue has only one space at the location 1. So the pointer variable REAR reset to 1 and store th...
The circular queue with the maximum capacity of n, the tail pointer of the queue is rear, and the head pointer of the queue is front,the condition for queue empty is ( ). A.A rear=front B.B (rear+1) MOD n=front C.C rear+1=front...
In the first condition, you will insert a new node into an empty queue. In this case, both the front and rear pointer must be Null. You must check it using the condition rear == -1. If it is true, the new element will be added as the first element of the queue, and both the...
A head pointer and a tail pointer are maintained to identify a head entry and a tail entry, respectively, within the queue. In response to an updating of at least one of the head pointer and the tail pointer, at least one of a near-full or a near-empty condition is detected. The ...
It has a fixed size array to hold elements. It has two members called start and end to point the index in the array to determine the front and the back of the queue. It also has the size member to save element count. At the beginning, we set start and end both to zero index. En...
Managing overflowOne must be able to handle the case where the queue is full and there is still incoming data. This case is known as the overflow condition. There are two methods which handle this case. They are to drop the latest data or to overwrite the oldest data. Either style may ...
