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; private DNode next; private DNode prev; }; class CDLinkedList { private: DNode head; // Dummy header node public CDLinkedList(); // Default constructor public bool insert (int val); //Inserts val at end into the linked list.Time complexity:O(1) public bool removeSecondLastValue (); //Note: Remove the Second last val from the linked list. Time complexity: O(1) };

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.
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. Thanks! I have to write the remove method in the code below. i attached the part where i need to write it. public class ourArrayList<T>{ private Node<T> Head = null; private Node<T> Tail = null; private int size = 0; //default constructor public ourArrayList() { Head = Tail = null; size = 0; } public int size() { return size; } public boolean isEmpty() { return (size == 0); } //implement the method add, that adds to the back of the list public void add(T e) { //HW TODO and TEST //create a node and assign e to the data of that node. Node<T> N = new Node<T>();//N.mData is null and N.next is null as well N.setsData(e); //chain the new node to the list //check if the list is empty, then deal with the special case if(this.isEmpty()) { //head and tail refer to N this.Head = this.Tail = N; size++; //return we are done.…
Create a class “Node” which is a single node of a singly linked list. 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.

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.
Given the interface of the Linked-List struct Node{ int data; Node* next = nullptr; }; class LinkedList{ private: Node* head; Node* tail; public: display_at(int pos) const; ... }; Write a definition for a method display_at. The method takes as a parameter integer that indicates the node's position which data you need to display. Example: list: 5 -> 8 -> 3 -> 10 display_at(1); // will display 5 display_at(4); // will display 10 void LinkedList::display_at(int pos) const{ // your code will go here }

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 accordingly
