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) {…
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.

Implement class “LinkedList” which has two private data members head: A pointer to the Node class length: length of the linked list // Node* GetNode(int index) const;A private function which is only accessible to the class methods. This function takes an array-like index and returns the address of the node at that index. 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 method: 1. bool RemoveHead();// Use RemoveAt FunctionRemove first node. Return true if successful, otherwise, false.2. bool RemoveEnd();// Use RemoveAt FunctionRemove last node. Return true if successful, otherwise, false.3 . void DisplayList() const;Display data of the whole linked list this in c++.

java program java method: Write a method replace to be included in the class KWLinkedList (for doubly linked list) that accepts two parameters, searchItem and repItem of type E. The method searches for searchItem in the doubly linked list, if found then replace it with repItem and return true. If the searchItem is not found in the doubly linked list, then insert repItem at the end of the linked list and return false. Assume that the list is not empty. You can use ListIterator and its methods to search the searchItem in the list and replace it with repItem if found. Do not call any method of class KWLinkedList to add a new node at the end of the list. Method Heading: public boolean replace(E searchItem, E repItem) Example: searchItem: 15 repItem: 17 List (before method call): 9 10 15 20 4 5 6 List (after method call) : 9 10 17 20 4 5 6
int F(node<int>&p){int c=0; while(p!=0){p=p->next; c++; } return c;} This function is a. return the number of items in the linked list b. return the number of items in a linked list and destroy the linked list c. None of these d. destroy the list and free all allocated nodes
Given main.py and a PersonNode class, complete the PersonList class by writing find_first() and find_last() methods at the end of the PersonList.py file. The find_first() method should find the first occurrence of an age value in the linked list and return the corresponding node. Similarly, the find_last() method should find the last occurrence of the age value in the linked list and return the corresponding node. For both methods, if the age value is not found, None should be returned. The program will replace the name value of each found node with a new name. Ex. If the input is: Alex 23 Tom 41 Michelle 34 Vicky 23 -1 23 Connor 34 Michela main.py(can not edit) from PersonNode import PersonNodefrom PersonList import PersonList if __name__ == "__main__": person_list = PersonList() # Read input lines until encountering '-1' input_line = input() while input_line != '-1': split_input = input_line.split(' ') name = split_input[0] age =…
Assume that the linked list class is ready and called (MyLinkedList) that contains nodes with int data, and next reference. Assume also that MyLinkedList contains only the following methods: addFirst(), addLast(), removeFirst(), removeLast(). Given that numbers are represented in linked lists (i.e. the number 567 will be represented in a linked list of three nodes; the first node contains 5, the second node contains 6 and the last node contains 7. Write a java method that receives the heads of two linked lists representing two numbers and finds the product (result of multiplication) list and returns its head. Note: You are free to use only one additional stack in your solution.
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
