q.enqueue(13);
q.enqueue(6);
q.enqueue(12);
q.dequeue();
q.dequeue();
q.enqueue(15);
q.enqueue(46);
q.dequeue();
q.enqueue(13);
q.enqueue(30);

- 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 data structure called a deque is closely related to a queue. The name deque stands for “double-ended queue.” The difference between the two is that with a deque, you can insert, remove, or view from either end of the queue. Implement a deque using arraysA deque data structure and a queue are related ideas. The abbreviation "deque" stands for "double-ended queue." A deque differs from the other two in that you may insert, remove, or view from either end of the queue. Implement a deque using arrays.
- b. Write out the order of elements that are contained in a queue after the following operations are performed. myQueue.enqueue(new Integer(16)); myQueue.enqueue(new Integer(12)); Integer num1 = myQueue.dequeue(); myQueue.enqueue(new Integer(6)); myQueue.enqueue(new Integer(8)); myQueue.enqueue(new Integer(30)); myQueue.enqueue(new Integer(24)); myQueue.enqueue(new Integer(18)); myQueue.dequeue(); myQueue.dequeue(); myQueue.dequeue(); myQueue.enqueue(new Integer(38); Show how step by step process of arriving at your answer.URGENT URGENT URGENT !!!! Write a void method swapStackwithQueue that takes MyStack and MyQueue Objects as parameters and exchanges the elements. a) The top element of the old stack becomes the rear element of the new queue. b b) and the rear element of the old queue becomes the top element of the new stack. The output should be similar to the image.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…
- 7. You could create a circular list from a single- linked list by executing the statement. а. tail.next = head b. head. prev = next c. tail. head next d. head.tail = prev 8. How much time does an ArrayList add a new element to the beginning of the list if n is the size of the ArrayList? а. О(1) b. 0(n) c. O(n²) d. 0(log n) 9. How much time does an ArrayList add a new element to the end of the list if n is the size of the ArrayList? a. 0(1) b. 0(n) c. O(n2) d. 0(log n)If the elements “A”, “B”, “C” and “D” are placed in a queue and are removed one at a time, in what order will they be removed?detemine if the follow statement are true or False and why? screenshots show the ArrayBoundedStack class and StackUnderflowException code If N represents the number of elements on the stack, then the push method of the ArrayBoundedStack class is O(N). While processing this expression ( } ( ) ( ) { { { } [ ] } } ) the highest number of elements on our stack at any one time is 1. If N represents the maximum possible number of elements on the stack, then the ArrayBasedStack constructor is O(N). The following expression is balanced: ( ( ( [ ) ] ) ) Our StackUnderflowException code essentially consists of two simple constructors and "packages" and "extends" statements and nothing else.
- Write a program for implementing queue using linked lists, for which you should use a structure to create a node with data and the next pointer. The program should be able to insert, delete and display nodes in the queue. The user will be asked to enter his choice either to insert a node (enqueue), delete a node (dequeue), display or to exit from the program.The options for the user should be as the following:1. Insert a node (Enqueue)2. Delete a node (Dequeue)3. Display4. Exit For example if user selected option 1 then the following should appear in the output:Enter the value to insert:Node is inserted If user selected option 2 then the following should appear in the output:Deleted Element is: If the user selected option 3 then the program should display the elements that are available in the queue The program will keep on running and taking inputs from the user until he selects the 4th option to exit.Write a program that creates a linked list to represent details of students. • SID (for Student ID) • Name • Address • Age • Gender Your program must also display a menu to perform the following tasks: • Create a linked list. The method to create a linked list makes use of the method insertFirst() or insertLast() or insertOrdered() • Insert new nodes to the linked list. • Search for details pertaining to a particular student. • Delete details of a particular student. • Find number of nodes in the linked list. • Display information pertaining to all students. The menu options should be as follows: 1. Create linked list 2. Add new student 3. Search for a student 4. Delete a student 5. Find number of students 6. Print student details 7. Exitin java language import java.util.ArrayList;import java.util.Arrays; Write the method named mesh.* * Start with two ArrayLists of String, A and B, each with * its elements in alphabetical order and without any duplicates. * Return a new list containing the first N elements from the two * lists. The result list should be in alphabetical order and without * duplicates. A and B will both have a size which is N or more. * Your solution should make a single pass over A and B, taking * advantage of the fact that they are in alphabetical order, * copying elements directly to the new list.* * Remember, to see if one String is "greater than" or "less than" * another, you need to use the compareTo() method, not the < or > * operators. * * Examples:* mesh(["a","c","z"], ["b","f","z"], 3) returns ["a","b","c"]* mesh(["a","c","z"], ["c","f","z"], 3) returns ["a","c","f"]* mesh(["f","g","z"], ["c","f","g"], 3) returns ["c","f","g"]* * @param a an ArrayList of String in alphabetical order.*…
