Implement a class for Circular Doubly Linked List (with a dummy header node) which
stores integers in unsorted order. Your class definitions should look like as shown below:
class CDLinkedList;
class DNode {
friend class CDLinkedList;
private:
int data;
DNode* next;
DNode* prev;
};
class CDLinkedList {
private:
DNode head; // Dummy header node
public:
CDLinkedList(); // Default constructor
bool insert (int val); // Inserts val into the linked list. Time complexity: O(1)
bool removeLastValue (int v);
//Note: Remove the last val from the linked list. Time complexity: O(1)
void findMiddleValue(); // find middle value of the linklist and delete it.
void display(); // Displays the contents of linked list on screen …
};

- Assume you have a class SLNode representing a node in a singly-linked list and a variable called list referencing the first element on a list of integers, as shown below: public class SLNode { private E data; private SLNode next; public SLNode( E e){ data = e; next = null; } public SLNode getNext() { return next; } public void setNext( SLNoden){ next = n; } } SLNode list; Write a fragment of Java code that would append a new node with data value 21 at the end of the list. Assume that you don't know if the list has any elements in it or not (i.e., it may be empty). Do not write a complete method, but just show a necessary fragment of code.package circularlinkedlist;import java.util.Iterator; public class CircularLinkedList<E> implements Iterable<E> { // Your variablesNode<E> head;Node<E> tail;int size; // BE SURE TO KEEP TRACK OF THE SIZE // implement this constructorpublic CircularLinkedList() {} // I highly recommend using this helper method// Return Node<E> found at the specified index// be sure to handle out of bounds casesprivate Node<E> getNode(int index ) { return null;} // attach a node to the end of the listpublic boolean add(E item) {this.add(size,item);return false; } // Cases to handle// out of bounds// adding to empty list// adding to front// adding to "end"// adding anywhere else// REMEMBER TO INCREMENT THE SIZEpublic void add(int index, E item){ } // remove must handle the following cases// out of bounds// removing the only thing in the list// removing the first thing in the list (need to adjust the last thing in the list to point to the beginning)// removing the last…Java programming language I have to create a remove method that removes the element at an index (ind) or space in an array and returns it.

The node stores an integer datatype. The class has two data members, an integer and pointer to the same Node class.Implement the following methods:1. The default constructor: Set value of the data member to zero2. A parameterized constructor: Node(int a); takes an integer variable and assigns it to the data member of this object. Set next pointer to NULL.3. Node* GetNextPointer() const; Retun next pointer of this Node4. void SetNextPointer(Node *ptr); Set the next pointer of this node to the ptr that is passed to the function.5. void SetData(int a); Set data of this node equal to ‘a’6. int GetData() const; returns the data of this object.The data member are private whereas the methods are public. part 4 5 and 6 In c++.4. Suppose our MyLinkedList class represented a doubly linked list, where each Node is implemented as follows: private class Node { Node prev, next; E element; } public Node (E element) { } this.element = element; Each Node has a reference to the previous Node as well as to the next Node in the list. MINIMALLY modify the add(int index, E element) method below to work properly with the doubly linked Nodes, and highlight or underline your changes.
- 2) Suppose you have a linked list class that provides the following methods: // constructor. // returns size of the list. LinkList () int size (); void insertHead (Object data) // insert new data at the head of // the list. // remove and return the Object at // the head of the list. Object removeHead () void insertTail (Object data) // insert new data at the tail of // the list. The class below is an implementation of a stack using the linked list class. Fill in the method implementations: class Stack { private Stack s; public Stack () { public void push (Object x) { } public Object pop () // assume stack is not empty { } public boolean isEmpty() { }In Java, Question 15: Answer the following questions You are asked to Implement an ADT for MyQueue. The following is a class definition of a linked list Node: class Node { String content; Node next; } The following is a class definition of a linked list MyQueue: class MyQueue { Node head; } Implement the following methods for your class MyQueue. a) Constructor that does not requre any parameters b) Constructor that accepts a parameter of type MyQueue and creates a new instance of MyQueue that is a clone of the one passed as parameter c) public int AppendCopy method that accepts a single parameter of type MyQueue and clones all elements from the MyQueue instance passed as a parameter and appends them to the instance on which we called the method. Return the number of elements that are cloned and appended d) public int FindElements(String filter) - finds all elements that match the filter and returns their count e) overload the FindElementsmethod to include a…Write a program that implements a double linked list. The MyLinked List class used in Listing 24.5 is a on-way directional linked list that enables one-way traversal of the list. Modify the Node class to add the new data field named previous to refer to the previous node in the list, as follows: public class Node { E element; Node next; Node previous; public Node (E e){ element = e; } } Implement a new class named TwoWayLinked List that uses a doubly linked list to store elements. Define TwoWayLinked List to implement MyList. You need to implmeent all the methods defined in MyLinkedList as well as the methods listIterator() and listInterator(int index). Both return an instance of java.util.ListIterator (see figure 20.4 in the text book). The former sets the cursor to the head of the list adn the latter to the element at the specified index.
- Java Program Consider a class Student that has an attribute age and a method getAge(): StudentList is a class representing a linkedlist of students. Write sumListAge_lterative......), a method that computes and returns the sum of the ages of all students in the list using the iterative way. Parameters of the method should be specified accordinglyIn c++ , write a program to create a structure of a node, create a class Linked List. Implement all operations of a linked list as member function of this class. • create_node(int); • insert_begin(); • insert_pos(); • insert_last(); • delete_pos(); • sort(); • search(); • update(); • reverse(); • display(); ( Drop coding in words with screenshot of output as well )Given the IntNode class, define the getCount() method in the CustomLinkedList class that returns the number of items in the list not including the head node. Ex: If the list contains: head -> 14 -> 19 -> 4 getCount(headObj) returns 3. Ex: If the list contains: head -> getCount(headObj) returns 0. public class IntNode { private int dataVal; // Node data private IntNode nextNodePtr; // Reference to the next node // Default constructor public IntNode() { dataVal = 0; nextNodePtr = null; } // Constructor public IntNode(int dataInit) { this.dataVal = dataInit; this.nextNodePtr = null; } // Constructor public IntNode(int dataInit, IntNode nextLoc) { this.dataVal = dataInit; this.nextNodePtr = nextLoc; } /* Insert node after this node.
