- #include <iostream> #include <queue> //This contains the STL's efficient implementation of a priority queue using a heap using namespace std; /* In this lab you will implement a data structure that supports 2 primary operations: - insert a new item - remove and return the smallest item A data structure that supports these two operations is called a "priority queue". There are many ways to implement a priority queue, with differernt efficiencies for the two primary operations. For this lab, please do not attempt (at least at first) to implement something fancy (like a heap). Just use your mind to do something simple. Analyze the efficiency of both insertion and removal for your implementation. Afterwards, feel free to investigagte "min heaps" to see a very clever and fast priority queue implementation. Feel free to try to implement it. After implementuing your priority queue, use it to implement a sorting algorithm (priorityQueueSort). Analyze the run time of your sorting…#include <iostream>using namespace std;class st{private:int arr[100];int top;public:st(){top=-1;}void push(int ItEM) {top++;arr[top]=ItEM; }bool ise() {return top<0;} int pop(){int Pop;if (ise()) cout<<"Stack is emptye ";else{Pop=arr[top];top--;return Pop;}}int Top(){int TOP;if (ise()) cout<<" empty ";else {TOP=arr[top];return TOP;}}void screen(){ for (int i = 0; i <top+1 ; ++i) {cout<<arr[i];} }};int main() {st c;c.push(1);c.push(2);c.push(3);c.push(4);c.pop();c.push(5);c.screen();return 0;} alternative to this code??Lab Goal : This lab was designed to teach you more about recursion.

You program should first prompt the user to enter how many numbers that will specify. The program should then scan for each number, separated by a newline. You should calculate the average value and return the number from the list which is furthest away from this average (to 2dp).
