Given the following definition of a single linked list, write a method that calculates and returns the sum of even integers in a linked list. public class SLL<E> { private static class Node<E>{ private E data; private Node<E> next; private Node(E dataItem) { data = dataItem; next = null; } private Node(E dataItem, Node<E> nodeRef) { data = dataItem; next = nodeRef; } } private Node<E> head = null; private int size = 0; }
Implement 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. Node* GetNode(int index) const;A private function which is only accessible to the class methods. . For example, index 0 corresponds to the head and index length-1 corresponds to end node of the linked list. The function returns NULL if the index is out of bound.Implement the following public methods:2. LinkedList();Constructor that sets head to NULL and length equal to zero.3. bool InsertAt(int data, int index);Insert a new node at the index. Return true if successful, otherwise,return false. The new node should be at the position “index” in the linked list after inserting it. You might have to use GetNode private function. these 3 parts
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++
Given main.py and a Node class in Node.py, complete the LinkedList class (a linked list of nodes) in LinkedList.py by writing the insert_in_ascending_order() method that inserts a new Node into the LinkedList in ascending order. Ex: If the input is: 8 3 6 2 5 9 4 1 7 the output is: 1 2 3 4 5 6 7 8 9 Code given
Java Given main() in the Inventory class, define an insertAtFront() method in the InventoryNode class that inserts items at the front of a linked list (after the dummy head node).
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 =…
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.

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.
Java Only Do Method, I will give LinkedList Implementation Write a method checkForEquality to be included in class KWLinkedList that does not have any parameter. Assume the list is having even number of nodes. The method returns true if the first half of the list is equal to the second half of the list in the reverse order, otherwise it returns false.
