Simulate a patient’s lines using queues with enqueue ( ), dequeue ( ) and printQueue ( ) operations. Define a queue node in the following manner: typedef struct queueNode { int patientID; // Unique identifier; starts at 1; after 24 hours should be reset to 1 int checkupTime; // Random time; int totalTime; // totalTime = checkupTime + sum of checkupTimes of patients in line //before this patient; units in minutes struct queueNode *pNext; } QueueNode;  You will randomly generate arrival times and checkup times of patients such that patients arrive every one to five minutes and their checkup …

Hi Team, Im reading Collections. It is mentioned that while intialising priority queue, it uses natural ordering by default. But my output is not like that. Below is my code and output. public class BackedCollections { public static void main(String[] args) { PriorityQueue<Integer> pq = new PriorityQueue<Integer>(); pq.offer(3); pq.offer(1); pq.offer(5); pq.offer(2); pq.offer(12); pq.offer(14); pq.offer(0); System.out.println(pq); } } ** OUTPUT ** [0, 2, 1, 3, 12, 14, 5] It Should be [0,1,2,3,5,12,15] right ? Please clarify

I need your help regarding the message acknowledgement in the queue when the message reaches at the queue. Any help would be highly appreciated. the code for my queue class is; struct ListNode { ListNode(gcroot<message^> msg); gcroot<message^> msg; ListNode* next; }; ListNode::ListNode(gcroot<message^> msg): msg(msg), next(nullptr) {} public class queue { public: queue(); ~queue(); bool Empty() const; void Enqueue(message^); void Dequeue(); void DisplayAll() const; private: // Disable copying to keep the example simple gcroot<String^> bindingkey; queue(queue const& obj); ListNode* head; ListNode* tail; gcroot<String^> name; // Added this }; queue::queue():head(nullptr), tail(nullptr) {} queue::~queue() { while (head != nullptr) { Dequeue(); } } …
