Given the following definition for a LinkedList: // LinkedList.h class LinkedList { public: LinkedList(); // TODO: Implement me void printEveryOther() const; private: struct Node { int data; Node* next; }; Node * head; }; // LinkedList.cpp #include "LinkedList.h" LinkedList::LinkedList() { head = nullptr; } Implement the function printEveryOther, which prints every other data value (i.e. those at the odd indices assuming 0-based indexing).
Course: Data Structure and Algorithms Language: C++ Question is well explained Question #2Implement 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 nodepublic CDLinkedList(); // Default constructorpublic bool insert (int val); public bool removeSecondLastValue (); public void findMiddleValue(); public void display(); };
Class Name: Exercise24_03 JAVA The MyLinkedList class used in LiveExample 24.5 is a one-way directional linked list that enables one-way traversal of the list. Modify the Node class to add the new data field name 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 TwoWayLinkedList that uses a doubly linked list to store elements. Define TwoWayLinkedList to implements MyList. You need to implement all the methods defined in MyLinkedList as well as the methods listIterator() and listIterator(int index). Both return an instance of java.util.ListIterator (see Figure 20.4). The former sets the cursor to the head of the list and the latter to the element at the specified index. Test your new class using this code from https://liveexample.pearsoncmg.com/test/Exercise24_03.txt. Sample output: Enter 5 integers: 1.23.45.67.89.11.2 3.4 10.55 7.8 9.1 9.1 7.8 10.55 3.4

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.
