Enqueue() andDequeue()are the primary operations of the queue, which allow you to manipulate the data flow. These functions do not depend on the number of elements inside the queue or its size; that is why these operations take constant execution time, i.e., O(1) [time-complexity]. He...
MyCircularQueue(k): Constructor, set the size of the queue to be k. Front: Get the front item from the queue. If the queue is empty, return -1. Rear: Get the last item from the queue. If the queue is empty, return -1. enQueue(value): Insert an element into the circular queue....
enQueue(value):This function is used to insert the new value in the Queue. The new element is always inserted from the rear end. deQueue():This function deletes an element from the Queue. The deletion in a Queue always takes place from the front end. Applications of Circular Queue The ...
3.) enqueue(item):-This function is used to insert an element with value item in the queue. 4.) dequeue():-This function is used to remove an element from the front of the queue. Code Snippet to enqueue an element in queue if((rear+1)% n != front) { rear =(rear+1)%n; Qu...

Firstly the queue is initialized to zero (i.e. empty). Determine whether the queue is empty or not. Determine if the queue is full or not. Insertion of the new element from the rear end (Enqueue). Deletion of the element from the front end (Dequeue). ...
