Knowledge in Priority Queue

Priority Queue using Linked List

#include <stdio.h> #include <stdlib.h>    // Node typedef struct node {     int data;        // Lower values indicate higher priority     int priority;        struct node* next;    } Node;    // Function to Create A New Node Node* newNode(int d, int p) {     Node* temp = (Node*)malloc(sizeof(Node));     temp->data = d;     temp->priority = p;     temp->next = NULL;        return temp; }    // Return the value at head int peek(Node** head) {     return (*head)->data; }    // Removes the element with the // highest priority form the list void pop(Node** head) {     Node* temp = *head;     (*head) = (*head)->next;     free(temp); }    // Function to push according to priority void push(Node** head, int d, int p) {     Node* start = (*head);        // Create new Node     Node* temp = newNode(d, p);        // Special Case: The head of list has lesser     // priority than new node. So insert new     // node before head node and change head node.     if ((*head)->priority > p) {            // Insert New Node before head         temp->next = *head;         (*head) = temp;     }     else {            // Traverse the list and find a         // position to insert new node         while (start->next != NULL &&                start->next->priority < p) {             start = start->next;         }            // Either at the ends of the list         // or at required position         temp->next = start->next;         start->next = temp;     } }    // Function to check is list is empty int isEmpty(Node** head) {     return (*head) == NULL; }    // Driver code int main() {     // Create a Priority Queue     // 7->4->5->6     Node* pq = newNode(4, 1);     push(&pq, 5, 2);     push(&pq, 6, 3);     push(&pq, 7, 0);        while (!isEmpty(&pq)) {         printf("%d ", peek(&pq));         pop(&pq);     }        return 0; }

Priority Queue Code KIIT UNIVERSITY

This is a code to get priority queue running in C.

data structures: queues code 2

Queue is a linear data structure where the first element is inserted from one end called REAR and deleted from the other end called as FRONT. ... In a queue, one end is always used to insert data (enqueue) and the other is used to delete data (dequeue), because queue is open at both its ends here we are implementing job allocation for staff memberrs using queues
