Then we got two display functions for both the different type types of a queue. The Size of array is 5 by default, to change, edit the second line of code.C program to implement DeQue using Array#include <stdio.h> #define MAX 5 int deque_arr[MAX]; int left = -1; int right = ...
Enqueue:This function is used to add an element to the rear end of the queue. If the queue is completely filled, then it will be in an overflow condition. The time complexity of the enqueue is O(1). Dequeue:This function is used to remove an element from the front end of the queue...
Therefore, the value of front will remain -1. However the value of rear increases by 1 every time whenever the insertion operation is performed in the queue. C++ Java Python #include <bits/stdc++.h> using namespace std; struct Queue { int front, rear, capacity; int* queue; Queue(int...

The complexity of enqueue and dequeue operations in a queue using an array isO(1). If you usepop(N)in python code, then the complexity might beO(n)depending on the position of the item to be popped. Applications of Queue CPU scheduling, Disk Scheduling ...
Stack: Implements a stack akin tostd::stackin C++. String: Implements a basic string class that mimicsstd::stringin C++. Vector: Implements a dynamic array similar tostd::vectorin C++. PriorityQueue: Implements a priority queue based onstd::priority_queuein C++. ...
Peek: Returns the object at the front of the queue without removing it. IsEmpty: Tests if the queue is empty or not. Size: Returns the total number of elements present in the queue. Practice this problem Queue Implementation using an array: 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15...
1.1 Basic FIFO Queue The Queue class implements a basic , container. Elements are added to one “end” of the sequence usingput(), and removed from the other end usingget(). The following is programming codes: import queue q = queue.Queue() ...
