Building a Priority Queue in C++ using a min-heap.

Not using C++ Standard Template Library.

Trying to understand how this works. Thank you

`Hey,

Note: Brother if you have any queries related the answer please do comment. I would be very happy to resolve all your queries.

#include <bits/stdc++.h>

using namespace std;

// Driver code

int main ()

{

// Creates a min heap

priority_queue <int, vector<int>, greater<int> > pq;

pq.push(5);

pq.push(1);

pq.push(10);

pq.push(30);

pq.push(20);

// One by one extract items from min heap

while (pq.empty() == false)

{

cout << pq.top() << " ";

pq.pop();

}

return 0;

}

Kindly revert for any queries

Thanks.

A max-heap can be used as a max-priority queue, which is an abstract data type having the operations Insert, Maximum, Extract-Max, and Increase-Key. a. Describe how to implement a FIFO queue with a priority queue, and analyze the time complexity of the implementation (Insert and Delete operations), assuming that a heap is used for the priority queue. b. Describe how to implement a LIFO queue (i.e. a stack) with a priority queue, and analyze the time complexity of the implementation...

One way to remove an object from a binary min heap is to decrease its priority value by 1 and then call deleteMin. An alternative is to remove it from the heap, thus creating a hole, and then repair the heap. Write pseudocode for an algorithm that performs the remove operation using the alternative approach described above. Your pseudocode should implement the method call remove (int index), where index is the index into the heap array for the object to...

Implement a priority queue using a DoublyLinkedList where the node with the highest priority (key) is the right-most node. The remove (de-queue) operation returns the node with the highest priority (key). If displayForward() displays List (first-->last) : 10 30 40 55 remove() would return the node with key 55. Demonstrate by inserting keys at random, displayForward(), call remove then displayForward() again. You will then attach a modified DoublyLinkedList.java (to contain the new priorityInsert(long key) and priorityRemove() methods). Use the provided...
