- QUESTION 9 Write a complete Java program to implement a QUEUE in a bank using LinkedList class as follows: • Provide the menu as shown below; use an infinite loop; stop when user opts 4. 1. Add a customer 2. Remove a customer 3. Show the queue 4. Exit • Add a customer should add an int number at the end of queue using the method addLast(). • Remove a customer should delete the int from front using the method removeFirst(). Show the queue should display the numbers in queue using the method System.out.printIn(). For the toolbar, press ALT+F10 (PC) or ALT+FN+F10 (Mac).An array of size MAX_SIZE is used to implement a queue. head, tail, and size are tracked. Suppose front is 0 and rear is MAX_SIZE -1. How many elements are present in the queue? a. 0 b. MAX_SIZE-1 c. MAX_SIZE d. 1The regular queue is a FIFO structure, meaning that you can only enqueue at the rear and dequeue at the front. Suppose that the dequeue operation can also be performed at the rear (so you can remove and return the last element on the queue), which of the following describes the correct and efficient way of using a linked list to implement this queue? OUsing a singly linked list with a reference to the head only, the dequeue method traverses it, stops at the last node and removes it. O Using a singly linked list with a reference to the head only, the dequeue method traverses it, stops at the second to last node and removes the last node. O Using a singly linked list with references that point to the first and the last nodes respectively, the dequeue method removes the last node via the corresponding reference. OUsing a doubly linked list with references that point to the first and the last nodes respectively, the dequeue method can remove the last node via the corresponding reference. O…
- In Java Implement a queue, add data to the queue and display ouput using buil-in functions using getMaxSize() and getCurrent Size()Reversing a queue can be simply done by dequeuing the queue until it's empty and then enqueuing the elements in the same order as they were dequeued. True FalsePlease Use Java language Write a method “mergeQueueStack” that takes a queue as a parameter of type: Queue of integers and a stack as a second parameter of type: Deque of integers Remove all the items from the queue and remove all the items from the stack then add them to a LinkedList by alternating between an item from queue then an item from stack. Don’t assume initially both the queue and the stack have the same number of items. The method should return the linked list of type integers. Example: If queue has : 1,2,3,4,5 and stack has 10, 20, 30 (where 10 is at top of the stack) then the linkedList should contain: 1,10,2,20,3,30,4,5
- If an array of size 6 is used to implement a circular queue, and the current values of rear and front are O and 3 respectively, when one element is removed from the queue and two more elements are added, what are the values of rear and front, respectively? O 1, 5 O 4, 2 5, 1 O 2, 3 None of the abovehow to create Circular Linked Queue without using a front reference that implements a queueinterface, also include a toString method that match the output: c d then write a driver program to test it?(note that front=rear.getLink()) the driver program should dequeue first element(use try catch) than enqueue a, enqueue b, dequeue, dequeue, enqueue c, enqueue d screen shot show the queueinterface and LLnodeImplement a method concatenate in class LinkedQueue. This method should take all the elements of a queue sourceQ and append them to the end of another queue targetQ. The operation should result in sourceQ being an empty queue. Test this method in the main method of LinkedQueue. package queues;public class LinkedQueue<E> implements Queue<E> { private SinglyLinkedList<E> list = new SinglyLinkedList<>(); // an empty list public LinkedQueue() { } // new queue relies on the initially empty list @Override public int size() { return list.size(); } @Override public boolean isEmpty() { return list.isEmpty(); } @Override public void enqueue(E element) { list.addLast(element); } @Override public E first() { return list.first(); } @Override public E dequeue() { return list.removeFirst(); } public String toString() { return list.toString(); }}
- Implementing a Stack ADT using a linked solution. The implementations are linked Nodes. class Node: def __init__(self, data, node=None): # Initialize this node, insert data, and set the next node if any self.data = data self.chain = node class SubSetStack: def __init__(self, data=None): # Initialize this stack, and store data if it exists def push(self, data): # Add data to the beginning of the stack def pop(self): # Remove the element at the beginning of the stack. # Return the data in the element at the beginning of the stack, or None if the stack is empty def top(self): # Return the data in the element at the beginning but does not remove it. # Return None if stack is empty. def __len__(self): # Return the number of elements in the stack def subset_sum(target, sub_list): # Returns True if Target can be formed from sub_list repeated # some arbitrary number of times. In the above function a Node…Find the error in each of the following code segments // A linked implementation of a queue int dequeue() { if(empty()) throw new EmptyQueueException(); int value = front.value; front ++; return value; }Consider the Queue ADT: Queue: enqueue(x) adds x to the back of the queue dequeue () removes element at the front of the queue size() returns number of elements in queue Select all options that allow for an efficient implementation based on the discussions from class. For any array implementation, you can assume the array is large enough so that making a larger one is not needed when pushing an item to the stack. You can assume that a linked list will have both a head and tail reference. Using an array with the front of the queue at the front of the array. Using an array with the front of the queue at the back of the array. Using a singly linked list with the front of the queue at the head of the list. Using a singly linked list with the front of the queue at the tail of the list. None of these choices allows for an efficient implementation of all methods.
