group of researchers hired you to develop a system to manage the execution of their computing jobs (tasks) in a piece of equipment. This cquipment can only execute one job at a time. Thus, you need to create a Queue class to queue jobs. The queue can be associated with one of the following strategies for selecting jobs: First In First Out (FIFO). Lowest First (LF), and Last In First Out (LIFO). Use the Strategy design pattern for representing these strategies and their association to Queue. Draw a UML diagram

- Using c++ I would like to implement a queue as a class with a linked list. This queue Is used to help the class print job in displaying things like: a confirmation of the job request received and the status ( denied/accepted) along with the details such as a tracking number, position in the queue( if accepted), reason for denial (if denied), etc. These classes will be used in a menu-driven application that has the following options: request a print job ask for the job name; the name may have blank spaces and consist of alphanumeric characters only, must start with a letter display a confirmation of the job request received and the status ( denied/accepted) along with the details such as a tracking number, position in the queue( if accepted), reason for denial (if denied), etc execute a print job (remove from the queue ) display a confirmation along with the tracking number, the name of the print job, and the number of print jobs currently in the queue display number of print…You want to buy a ticket for a well-known concert which is happening in your city. But the number of tickets available is limited. Hence the sponsors of the concert decided to sell tickets to customers based on some priority. A queue is maintained for buying the tickets and every person is attached with a priority (an integer, 1 being the lowest priority). The tickets are sold in the following manner - 1. The first person (pi) in the queue requests for the ticket. 2. If there is another person present in the queue who has higher priority than pi, then ask pi to move at end of the queue without giving him the ticket. 3. Otherwise, give him the ticket (and don't make him stand in queue again). Giving a ticket to a person takes exactly 1 minute and it takes no time for removing and adding a person to the queue. And you can assume that no new person joins the queue. Given a list of priorities of N persons standing in the queue and the index of your priority (indexing starts from 0). Find…Hospital XX has a program to manage patient queues with the following criteria:1.

- The implementation of a queue in an array, as given in this chapter, uses the variable count to determine whether the queue is empty or full. You can also use the variable count to return the number of elements in the queue. On the other hand, class linkedQueueType does not use such a variable to keep track of the number of elements in the queue. Redefine the class linkedQueueType by adding the variable count to keep track of the number of elements in the queue. Modify the definitions of the functions addQueue and deleteQueue as necessary. Add the function queueCount to return the number of elements in the queue. Also, write a program to test various operations of the class you defined.A readinglist is a doubly linked list in which each element of the list is a book. So, you must make sure that Books are linked with the previous prev and next element. A readinglist is unsorted by default or sorted (according to title) in different context. Please pay attention to the task description below. Refer to the relevance classes for more detail information. Implement the add_book_sorted method of the ReadingList class. Assume the readinglist is sorted by title, the add_book_sorted method takes an argument new_book (a book object), it adds the new_book to the readinglist such that the readinglist remain sorted by title. For example, if the readinglist contain the following 3 books: Title: Artificial Intelligence Applications Author: Cassie Ng Published Year: 2000 Title: Python 3 Author: Jack Chan Published Year: 2016 Title: Zoo Author: Cassie Chun Published Year: 2000 If we add another book (titled "Chinese History"; author "Qin Yuan"; and published year 1989) to the…In a bank, customers wait in a queue (q0) for their turn to complete a transaction. Customers who come first are served first. At a certain point when there are lots of customers waiting, a decision is taken to split the queue elements into two empty queues q1 and q2. The customers are split based on the alphabetical order of their first names. Customers with first name starting A-H are added to q1 while the others (first name starting I-Z) are added to q2. In an application, write a method named splitQueue (in an application) that accepts as parameters 3 queues, the original queue (q0) and two empty queues (q1 and q2) to be filled as described above. Write also a main method in which you read the first names of customers from the user, fill them into q0 and call the method splitQueue to split q0 elements into q1 and q2. After the split display the elements of q1 first then those of q2. The header of the method is: public static void splitQueue ( Queue q0, Queue q1, Queue q2) Note:…
- The priority queue is an abstract data type that contains the following methods: insert(item, priority Value) Inserts item into the priority queue with priority value priority.Value. peek() Returns (but does not remove) the item with highest priority in the priority queue. delete() Removes and returns the item with highest priority in the priority queue. changePriority(item, newPriority) Changes the priority of an item to a new priority value. Write down the algorithm and implement a priority queue (both min and max) using a heap tree-based data structure (both min and max). Determine the runtime for each of the following: 1. In the worst case, describe the runtime to insert an item into the priority queue. 2. In the worst case, describe the runtime to remove the element with highest priority. 3. In the worst case, describe the runtime to change the priority of an element. Show an example for each.In Java. Design and implement an application that simulates the customers waiting in line at a bank. Use a queue data structure to represent the line. As customers arrive at the bank, customer objects are put in the rear of the queue with an enqueue operation. When the teller is ready to service another customer, the customer object is removed from the front of the queue with a dequeue operation. Randomly determine when new customers arrive at the bank and when current customers are finished at the teller window. Print a message each time an operation occurs during the simulation. Add and remove tellers. Then control how efficient each teller is (when instantiating a new teller, there will be a parameter to control the relative speed of each teller. You will still use random values, but will multiply them them with some coefficient based on a given teller's "speed"Queues are often used to simulate situations where people have to wait in line. One scenario we can simulate with a queue is the annual Single’s Night dance at the Elks Lodge. Men and women enter the lodge and stand in line. The dance floor is quite small and there is room for only three couples at a time. As there is room on the dance floor, dance partners are chosen by taking the first man and woman in line. These couples are taken out of the queue and the next set of men and women are moved to the front of the queue. As this action takes place, the program announces the first set of dance partners and who the next people are in line. If there is not a complete couple, the next person in line is announced. If no one is left in line, this fact is displayed.First, let’s look at the data we use for the simulation:F Jennifer IngramM Frank OpitzM Terrill BeckermanM Mike DahlyF Beata LovelaceM Raymond WilliamsF Shirley YawM Don GundolfF Bernica TackettM David DurrM Mike McMillanF Nikki…
- on c++ visual studio: for queue implementation: Enqueue some numbers, then dequeue them, later enqueue some others as well. Finally, keep on dequeueing until the queue is empty. You should be printing out every operation of enqueue or dequeue: Ex: Enqueueing 8... Dequeueing 8... Enqueueing 14.... Enqueueing 20.... Dequeueing 14.... Dequeueing 20.... Queue is empty.In Java In the real world, you will often be tasked with understanding and improving another person’sinelegant, hard-to-understand code. This project provides practice for that type of work.The given program, shown below, implements a circular-array queue. A queue is a British term for aline of people waiting to be served. A queue can also refer to any line of items where the item at thefront of the queue is served next, and new items are added at the rear of the queue. Informationtransmission systems, like the Internet, have lots of queues, where messages in transit are temporarilystalled at some intermediate system node, waiting to get into the next available time slot on the next legof their journey. A queue’s length is the total number of people or items currently waiting. When thenext item is served, that shortens the queue by one. When another person arrives, that lengthens thequeue by one. A queue’s capacity is the maximum number of items that can fit in the line at one time.If…you are to design a printer queue that is responsible for handling the printing requests coming from different users. You have to take into consideration that users have different levels of priorities. Each user has an identification number and a password, in addition to printing priorities. One good idea is to design the queue using an array or pointers while preserving the first-in first-out concept of the queue. For every printing request received, the program should check the priorities of that request and whether it can be moved forward in the queue to be served by the printer prior to serving the other requests. Using the programming language of your choice (preferably C++), write the printer queue that would handle the user request. The program must allow for requests coming from different users or from one user. Note: I need a working C++ code for this problem, and i need priorities.
