Priority Queue is a data structure that plays a very pivotal role as it helps the elements get arranged in a sorted manner without using any external sorting algorithm just with the help of internal heap and queue data structure within the container or the queue. Check out this tutorial to learn about how a priority queue works and how it can be implemented in different programming languages. This program swaps the elements present in one priority queue with the elements present in the other priority queue condition applies that there should be two priority queue present to perform this function. If there are two priority queues present and It is a requirement to replace the elements of one priority queue with the elements of another priority queue then that function will be taken as a parameter for the priority queue. This program describes the insertion of elements within the priority queue and then displaying the elements. This method will help in pushing or inserting the elements within the priority queue. This program helps to determine the size of the priority queue using size() function. ![]() Size() method in C++ will return the actual size of the Priority Queue. There are some specific methods which are being used are as follows: 1. ![]() Therefore it has to be kept as a point that there is no special algorithm that is being followed but yes priority queue supports heaps as a structure based on how the heap structured in a tree format having the child elements nodes arranged in a heap with respect to parent nodes being divided into 2 parts of Min heap and Max heap respectively. Let’s make it more clear suppose we will insert elements like 5,50,14,20,35 in the priority queue or the container then that priority queue will make use of push function and then pop the elements using the pop function with output in a manner 50,35,20,14,5.īut then again one more point comes into the mind like how this sorting of elements is working. It is very much important to include one header file in the program with respect to the priority queue. The first element to be inserted should be the greatest because that element will be compared with the other elements and then one element will be returned in a sorted manner. Working of Priority Queue can be explained giving a scenario where a container will be taken into consideration where elements will be given as an input to the container in a way where the elements will have an order of non-increasing manner i.e. The criteria make use of min-heap and max-heap respectively to maintain the order. Note: Priority Queue does not follow any kind of sorting algorithms rather it stores the elements in the form of the heap.
