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 =…
Using a doubly linked list class and node class, implement the following methods: Node* lastNode(void); void pushBack(string argData); void popBack(void); void pushFront(string argData); void print(void); void printReverse(void); void insertAfter(Node* argPtr); void deallocateAll(void); Node* searchFor(string argData); int size(void); Hard code a linked list (no UI) in the main to demonstrate your functions. Print forward and backward to show that the links are well-formed.
Given two linked lists sorted in increasing order, write a method intersection( ) to return a new list representing the intersection of the two lists. The new list should be made with its own memory — the original lists should not be changed. Example: if list1 contains {3,4,7,9,11} and list contains {2,3,8,9,12,15} so the intersection list3 is {3,9}.
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…
Assume that the following method is added to the class KWLinkedList. What does this method do? public boolean question() { if (size%2 == 1 || size < 2) return false; Node<E> h = head; for(int i = 0; i < size/2; i++) h=h.next; Node<E> p = head; while (h!= null) { if (! p.data.equals(h.data)) return false; p = p.next; h = h.next; } return true; } Compare the elements of the first half of the list with the second half, if any one node has the same data value, it will return false, else it will return true. Compare the elements of the first half of the list with the second half, if all the nodes have the same data values, it will return true else, it will return false. Compare the elements of the first half of the list with the second half, if all the nodes have the same data values, it will return false else, it will return true…
In java, how do I implement the following methods into a linkedlist class. 1) removeLast() – remove the last number of the list 2) removeLeast()- remove least number in the list 3) removeMax()- remove largest number in the list 4) removeFirst() – remove the first number of the list 5) addNum()- add another number to the list
/ This method takes as parameters a reference to the head of a linked list, a // position specified by n, and a key. It returns the number of occurrences // of the key in the linked list beginning at the n-th node. If n = 0, it means // you should search in the entire linked list. If n = 1, then you should skip // the first node in the list. public int numOccurrencesRec(LNode node, int n, int key) { // TODO: implement this method return 0; // replace this statement with your own return } } LNode Below: public class LNode{ // instance variables private int m_info; private LNode m_link; // constructor public LNode(int info) { m_info = info; m_link = null; } // member methods public void setLink(LNode link) { m_link = link; } public LNode getLink() { return m_link; } public int getInfo() { return m_info; } }
Implement a class “LinkedList” which has two private data members head: A pointer to the Node class length: length of the linked listImplement the following private method: 1. bool InsertHead(int data); // Use InsertAt FunctionInsert at the start of the linked list. Return true2. bool InsertEnd(int data); // Use InsertAt FunctionInsert at the end of the linked list. Return true3. bool RemoveAt(int index);Remove and delete the node at position “index”. Return true if successful, otherwise, false. this in c++
Java 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 Second image is ItemNode

1- A new static method with one parameter which is a head node for a linked list of integers, the method should create a new linked list which is equivalent to the original list of integers but with all repetitions removed, the method's return value is a head reference for the new list. this is what I have but it's not removing repetitions. public static IntLinkedBag removeRepetition (IntLinkedBag b1) {    IntNode next;    IntNode head = null;    LinkedList<Integer> s = new LinkedList<>();    IntNode new_list = new IntNode(0, null);    IntNode now = head;    IntNode prev = new_list;    while (now!= null) {    int x = now.data;    if (s.contains(x)) {    new_list = new_list.next;    }    else {    s.add(x);    new_list.next = new IntNode(x, now);    new_list = new_list.next;    }    now = now.next;    }    return b1;    } }…
java program : Given the following method to be considered within the SingleLinkedList class, what does this method do? public void Undefined() {      Node<E> ptr = head;      if (ptr == null || ptr.next == null) return false;      E item1 = ptr.data;      while (ptr.next != null)            ptr = ptr.next;      E item2 = ptr.data;      if (item1.equals(item2))      {              head = head.next;              size--;      } } If the first element of the list is equal to the second element of the list, then the method deletes the second node. If the first element of the list is equal to the last element of the list, then the method deletes the first node. If the first element of the list is equal to the second element of the list, then the method deletes the first node. If the first element of the list is equal to the last element of the list, then the method deletes the last node.
