- In the existing CircularlyLinkedList class, Write a non-static method named getMax for finding the maximum element in a circularly linked list. Write the testing code in the main method of the class CircularlyLinkedList. For this purpose, you must only use and update the CircularlyLinkedList.java file provided in Lesson3Examples posted in the eCentennialmodule "Lesson Examples (from textbook)" package exercise3; public class CircularlyLinkedList<E> { private static class Node<E> { private E element; private Node<E> next; public Node(E e, Node<E> n) { element = e; next = n; } public E getElement() { return element; } public Node<E> getNext() { return next; } public void setNext(Node<E> n) { next = n; } } private Node<E> tail = null; private int size = 0; public CircularlyLinkedList() { } public int size() { return size; } public boolean isEmpty() { return size == 0; } public E first() { if (isEmpty()) return null; return…Given the MileageTrackerNode class, complete main() in the MileageTrackerLinkedList class to insert nodes into a linked list (using the insertAfter() method). The first user-input value is the number of nodes in the linked list. Use the printNodeData() method to print the entire linked list. DO NOT print the dummy head node. Ex. If the input is: 3 2.2 7/2/18 3.2 7/7/18 4.5 7/16/18 the output is: 2.2, 7/2/18 3.2, 7/7/18 4.5, 7/16/18 public class MileageTrackerNode { private double miles; // Node data private String date; // Node data private MileageTrackerNode nextNodeRef; // Reference to the next node public MileageTrackerNode() { miles = 0.0; date = ""; nextNodeRef = null; } // Constructor public MileageTrackerNode(double milesInit, String dateInit) { this.miles =…In the existing DoublyLinkedList class, write and test a non-static method named reverseList to reverse a doubly linked list. Write the testing code in the main method of the class DoublyLinkedList. For this purpose, you must only use and update the DoublyLinkedList.java file provided in Lesson2Examples posted in the eCentennial module “Lesson Examples (from textbook)” package Ex2; public class DoublyLinkedList<E> { private static class Node<E> { private E element; // reference to the element stored at this node private Node<E> prev; // reference to the previous node in the list private Node<E> next; // reference to the subsequent node in the list public Node(E e, Node<E> p, Node<E> n) {element = e;prev = p;next = n;} // public accessor methodspublic E getElement() { return element; } public Node<E> getPrev() { return prev; } public Node<E> getNext() { return next; } // Update methodspublic void setPrev(Node<E> p) { prev = p; }…
- Trying this again since part of my question keeps disappearing Given main() in the ShoppingList class, define an insertAtEnd() method in the ItemNode class that adds an element to the end of a linked list. DO NOT print the dummy head node. Ex. if the input is: 4 Kale Lettuce Carrots Peanuts where 4 is the number of items to be inserted; Kale, Lettuce, Carrots, Peanuts are the names of the items to be added at the end of the list. The output is: Kale Lettuce Carrots Peanuts public class ItemNode { private String item; private ItemNode nextNodeRef; // Reference to the next node public ItemNode() { item = ""; nextNodeRef = null; } // Constructor public ItemNode(String itemInit) { this.item = itemInit; this.nextNodeRef = null; } // Constructor…You are going to implement a program that creates an unsorted list by using a linked list implemented by yourself. NOT allowed to use LinkedList class or any other classes that offers list functions. It is REQUIRED to use an ItemType class and a NodeType struct to solve this homework. The “data.txt” file has three lines of data 100, 110, 120, 130, 140, 150, 160 100, 130, 160 1@0, 2@3, 3@END You need to 1. create an empty unsorted list 2. add the numbers from the first line to list using putItem() function. Then print all the current keys to command line in one line using printAll(). 3. delete the numbers given by the second line in the list by using deleteItem() function. Then print all the current keys to command line in one line using printAll().. 4. putItem () the numbers in the third line of the data file to the corresponding location in the list. For example, 1@0 means adding number 1 at position 0 of the list. Then print all the current keys to command line in one…Write a method called swapItems to be considered within the SingleLinkedList class that takes two parameters, index1 and index2 of type integer. The method swaps the data of the nodes at the given indexes. If any of the parameters indexes is invalid throw IndexOutOfBoundsException. Do not call any method of class SingleLinkedList in your method. Method heading: public void swapItems(int index1, int index2) Example: index1 = 2 index2 = 4 Before method call: list: 5 10 12 9 11 7 After method call: list: 5 10 11 9 12 7
- Python For this assignment, you will write a program to allow the user to store the names and phone numbers of their contacts. Create the following classes: Contact: two attributes. One for the contact's name and the contact's phone number. Node: two attributes: _data and _next. For use in a linked list. ContactList: One attribute: _head, a reference to the head of an internal linked list of Node objects. Note: self._head is an attribute of the class, so any method which updates the internal linked list can simply update the list self._head references. There is no need to return anything like we did in methods such as add_to_end in the lecture. Note also that for the same reason, we do not have to pass a reference to the head of the list to any method, because each method should already have access to the self._head attribute. ContactList should also have the following methods: add(name, new_number). Creates a new Node with a Contact object as its _data. The new Node is then added…Given main() in the ShoppingList class, define an insertAtEnd() method in the ItemNode class that adds an element to the end of a linked list. DO NOT print the dummy head node. Ex. if the input is: 4 Kale Lettuce Carrots Peanuts where 4 is the number of items to be inserted; Kale, Lettuce, Carrots, Peanuts are the names of the items to be added at the end of the list. The output is: Kale Lettuce Carrots Peanuts public class ItemNode { private String item; private ItemNode nextNodeRef; // Reference to the next node public ItemNode() { item = ""; nextNodeRef = null; } // Constructor public ItemNode(String itemInit) { this.item = itemInit; this.nextNodeRef = null; } // Constructor public ItemNode(String itemInit, ItemNode nextLoc) {…There’s a somewhat imperfect analogy between a linked list and a railroad train, where individual cars represent links. Imagine how you would carry out various linked list operations, such as those implemented by the member functions insertFirst(), removeFirst(), and remove(int key) from the LinkList class in this hour. Also implement an insertAfter() function. You’ll need some sidings and switches. You can use a model train set if you have one. Otherwise, try drawing tracks on a piece of paper and using business cards for train cars.
- How to answer the following questions? Here is a, possibly flawed, approach for using a traversal to print the contents of the linked list of strings accessed through letters. Indicate the description that best matches the code. LLNode<String> currNode = letters; while (currNode != null) { System.out.println(currNode.getInfo()); if (currNode.getLink() != null) currNode = currNode.getLink(); else currNode = null; } A. very good B. correct but inefficient C. correct but too complex D. will bomb if list is empty E. will bomb if list is not empty What is the result of evaluating the following postfix expression? 6 4 + * 3 10 + A. 0 B. 3 C. too many operands D. too few operands stack implementations throw an exception if a pop is attempted on an empty stack. A valid alternate approach to handling this situation is to: A. ignore it B. state as a precondition that pop will not be attempted on an empty stack. C. have the pop operation return a boolean indicating success.…Given the following definitions that we have used in class to represent a doubly-linked, circular List with a dummy-header node that contains data of type "struct Student". typedef struct { char *name; char *major; } Student;typedef struct node { Student *data; struct node *next; struct node *prev; } Node;typedef struct { Node *header; int size; } LinkedList;LinkedList *roster; Here is a picture of what the Linked List might look like, although you should answer the following question for a general list (ie, that does not necessarily contain 3 data items).
