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…
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 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). Ex. If the input is: 4 plates 100 spoons 200 cups 150 forks 200 the output is: 200 forks 150 cups 200 spoons 100 plates public class InventoryNode { private String item; private int numberOfItems; private InventoryNode nextNodeRef; // Reference to the next node public InventoryNode() { item = ""; numberOfItems = 0; nextNodeRef = null; } // Constructor public InventoryNode(String itemInit, int numberOfItemsInit) { this.item = itemInit; this.numberOfItems = numberOfItemsInit; this.nextNodeRef = null; } // Constructor public InventoryNode(String itemInit, int…

You might have heard about the "Guess the Word Game", so in this game the user has to guess the letter(s) of the word one by one. There are n chances given to guess its letters where n is the number of letters in that word. You have to implement given scenario with the help of “Doubly Linked List”. Create two linkedlist, first linkedlist will be containing of complete word e.g. ELEPHANT and second linkedlist will be containing of word but having some blank letters e.g. _LEP_AN_. You have to ask user for input for every letter and insert into second linkedlist as follows: Step 1: Letter 1: Insert into second linkedlist on first place and compare 1st value of first and second linkedlist if same then go to step 2 else go to step 1 Step 2: Letter 2: Insert into second linkedlist on fifth place and compare 5th value of first and second linkedlist if same then go to step 3 else go to step 2 Step 3: Letter 3: Insert into second linkedlist on last place and compare last value of…
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.…
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…

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++
IN JAVA, WRITE A CUT METHOD ABOUT THE INSTRUCTIONS BY USING FIRST, NEXT, NODE ext. DO IT UNDER THE CODE BELOW, public class GenericCollection<T> { private Node first; private Node last; private int count; private classNode { T data; Node next; } public GenericCollection<T> cut(int k) { //WRITE HERE PLEASE }
Implement an instance method, called getFirstHalf, that belongs to yourThingLinkedBag. The method returns as output a linked list that includes allvalues in the first half of the bag's linked list. For example, for the following bag3-->5-->8-->9. the method returns 3-->5.If the bag includes an odd number of nodes, then the middle element belongs tothe first half and is included in the output.Make sure to include the methodheader. The bag should remain unchanged (i.e., do not remove the returnedvalues from the bag).
