- Java adt Draw the contents of the queue after the following statements execute. Clearly label the front and back of the queue. QueueInterface bankLine = new LinkedQueue<>(); bankLine .enqueue("John"); bankLine .enqueue("Matthew"); String next = bankLine .dequeue(); next = bankLine .dequeue(); bankLine .enqueue("Drew"); bankLine .enqueue("Heather"); next = bankLine .dequeue(); bankLine .enqueue("David"); next = bankLine .dequeue();A number means to push and a dash means pop in the following sequence. Give the sequence of values returned by the pop operations when this sequence of operations is performed on an initially empty queue. 1 4 5 - - 6 7 8 - - - 2 6 - 12 10 - - -Using python 1. Create a stack class using linked list. 2. Provide samples of push, pop; and 3. Using your new class, add a method that reverses a given string without using any built-in reverse methods. Use string below as an example. str_sample = 'Did Hannah see bees? Hannah did.' 4. Create a queue class using linked list. 5. Provide samples of enqueue, dequeue; and 6.Zack and Aerith are set to be married. Lined up in front of them will be the entourage of their closest friends composed of 5 pairs. Biggs and Jessie will march first. Announce their names by pair using queues (i.e. use print)! Make sure to use enqueue and dequeue methods! men = ['Zack', 'Cloud', 'Barret', 'Vincent', 'Cid', 'Biggs'] women = ['Aerith', 'Tifa', 'Marlene', 'Lucrecia', 'Yuffie', 'Jessie'] # Example # "Zack and Aerith!" # "Cloud and Tifa!"
- 1a. What is a stack? b. Write an algorithm for all operations in the stack? 2a.What is a queue? b. Write an algorithm for all operations in the queue?USING PYTHON Create a queue class using Python lists under the hood. Make sure built-in list methods are not accessible when using the new queue object so its properties are not violated. Zack and Aerith are set to be married. Lined up in front of them will be the entourage of their closest friends composed of 5 pairs. Biggs and Jessie will march first. Announce their names by pair using queues (i.e. use print)!

- Assume q1 is a queue created in the main and q2 is created in a block scope and we write q2=q1 and in the main function we print the items of the q1, if no operator= overload method then then Select one: a. The q1 has the same items of q2 b. The q1 items becomes rubbish c. The q1 becomes empty d. The q1 was not changedclass Queue { private static int front, rear, capacity; private static int queue[]; Queue(int size) { front = rear = 0; capacity = size; queue = new int[capacity]; } // insert an element into the queue static void queueEnqueue(int item) { // check if the queue is full if (capacity == rear) { System.out.printf("\nQueue is full\n"); return; } // insert element at the rear else { queue[rear] = item; rear++; } return; } //remove an element from the queue static void queueDequeue() { // check if queue is empty if (front == rear) { System.out.printf("\nQueue is empty\n"); return; } // shift elements to the right by one place uptil rear else {…1. Suppose you have a circular queue of size 6 (1 to 6). Initially the value of thefront and rear is 0. Now show the state of the queue if the following operationis performed on the queue. Also find the value of front and rear in each step.insert (10); insert (5), delete (), insert (9); insert (9); insert (7); insert (5); insert(8); insert (10); insert (11).
- In C++, Write a program which is menudriven ( i) Enque, ii) Deque, iii) Peek iv) Print). It will create a circularQueue of integer type data using array. You have to implement the followingoperations.a. Enqueue (Insert a data to the queue)b. Dequeue (Remove an item from the queue and printit)c. Peek (Print the item at the Front)Print (Print the elements present at the queue)Implement a Queue using a vector or the STD ::queue:: class Note the difference in what it takes to implement using a char[] array vs a vector or the STD ::queue:: class The user will input a string and the program will return the string with each letter in the string duplicated. Displaying correct Queue implementation. Utilize the conventional methods as needed. Sample Execution Please input String: happy Program will produce the output string. Only use the enqueue(), dequeue(), empty(), etc hhaappyy26( How many Elements are there in the Queue? What will be the output of the following Algorithm on the given Queue?
