Queue in C is a data structure that is not like stack and one can relate the behavior of queue in real -life. Unlike stack which is opened from one end and closed at the other end which means one can enter the elements from one end only. Therefore, to overcome the scenario where we...
Queue Implementation using Two Stacks in C++: Here, we are going to implement a C++ program to implement Queue using two Stacks.

Let us see the following implementation to get a better understanding −Live Demo#include <bits/stdc++.h> using namespace std; void print_vector(vector<vector<auto> > v){ cout << "["; for(int i = 0; i<v.size(); i++){ cout << "["; for(int j = 0; j <v[i].size()...

Queue Complete ImplementationFollowing are the complete implementations of Queue in various programming languages −C C++ Java Python Open Compiler #include <stdio.h> #include <string.h> #include <stdlib.h> #include <stdbool.h> #define MAX 6 int intArray[MAX]; int front = 0; int rear ...
Python’s queue module provides an implementation of the Priority Queue data structure. See it in the following example:import queue # Create an empty priority queue my_priority_queue = queue.PriorityQueue() # Add tasks to the priority queue with their priority my_priority_queue.put((2, "...

Due to this property, dequeue may not follow the first in first out property. Queue implementation using Array: For the implementation of queue, we need to initialize two pointers i.e. front and rear, we insert an element from the rear and remove the element from the front, and if we ...
