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....
Algorithm for Enqueue OperationFollowing are the steps to perform the enqueue operation on a circular queue:1.Initialize an array or any data structure to store the elements of the circular queue. 2.Initialize two variables front and rear. 3.Check if the circular queue is full. 4.If it is...
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...
The queue status is read by a transmit scheduler and updated by another process that processes enqueue and dequeue requests (often referred to as a queue manager). The timing of these operations can cause a race condition in which the transmit scheduler reads a queue status modified by the ...
#include <bits/stdc++.h> using namespace std; class Queue { int rear, front; int size; int *arr; public: Queue(int s) { front = rear = -1; size = s; arr = new int[s]; } void enQueue(int value); int deQueue(); void displayQueue(); }; void Queue::enQueue(int value) ...
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 ...
Enqueue P(sL,s) and P(s,sR) in a queue. Assign unique colours from {χr(G)−|A(sL,s,sR)|+1,…,χr(G)} to the vertices of A(sL,s,sR). As long as the queue is nonempty, dequeue a piece P=P(s1,s2). If there are two pointers from P=P(s1,s2), say to P(s1,s...
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). ...
