- 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(); };7. ASK class DoublyLinkedList<E> {// define ListNode elements specific for this type of list, indicating current, previous and next// consider head as name for previous node, and tail for the next one.private ListNode<E> head;private ListNode<E> current;private ListNode<E> tail; // default constructorpublic DoublyLinkedList(){//*** Task #1: implement a default constructor here, initializing the nodes to null } // method that calculates the length of the listpublic int length(){//*** Task #2: implement the method navigating through the list until you run out of elements } // method that adds a node at the beginning of the listpublic void addANodeToStart(E addData){//*** Task #3: implement this method, taking into consideration that the head will be replaced by a new node. You may want to use a temporary variable } // accessor method that gets data at current nodepublic E getDataAtCurrent(){//*** Task #4: implement this method making sure to take into account…5. A linked list that stores int values would be comprised of a group of Nodes. Wemight define the Node by A. class Node {Node next;}B. class Node{int next;} C. class Node { int data; D. class Node { int data;Node next; }
- Data Structute Using c++ Queue The Full Question is on the Picture I need to continue on this code please ::: #include <iostream> using namespace std; struct node{int data;node *next;node(int d,node *n=0){data=d;next=n;}}; class queue{node *front,*rear;public:queue();bool empty();void append(int el);bool serve();bool retrieve(int &el);//destructor ...}; bool queue::empty(){return front==0;} queue::queue(){front=rear=0;} void queue::append(int el){if(front==0)front=rear=new node(el);elserear=rear->next=new node(el);} bool queue::serve(){if(front==0)return false;if(front==rear){delete front;front=rear=0;}else{node *t=front;front=front->next;delete t;}return true;} bool queue::retrieve(int &el){if(front==0)return false;el=front->data;return true;} int main (){QueueLinked<int> custQ; // Line (queue) of customers containing the QueueArray<int> custQ; // Line (queue) of customers containing the// time that each customer arrived and// joined the…Multiple choice in data structures void doo(node<int>*root){ if(root !=0) { node<int>*p=root; while(root->next!=0) root=root->next; p->data=root->data; } What is this code do? a. swap the first item with the last item in the linked list b. set the first item in the linked list as the last item c. doesn't do anything because the root parameter is passed by value d. change the root item in the binary tree with the farthest leaf item6. Suppose that we have defined a singly linked list class that contains a list of unique integers in ascending order. Create a method that merges the integers into a new list. Note the additional requirements listed below. Notes: ● . Neither this list nor other list should change. The input lists will contain id's in sorted order. However, they may contain duplicate values. For example, other list might contain id's . You should not create duplicate id's in the list. Important: this list may contain duplicate id's, and other list may also contain duplicate id's. You must ensure that the resulting list does not contain duplicates, even if the input lists do contain duplicates.

The implementation will contain a Node class that will store the data value and a link to the next node in the list. The size of the list can be computed by counting the nodes in the list in O(1) time.C++ The List class represents a linked list of dynamically allocated elements. The list has only one member variable head which is a pointer that leads to the first element. See the following code for the destructor to List. ~ List () { for (int i = 0; i <size (); i ++) { pop_back (); } } What problems does the destructor have? Select one or more options: 1. There are no parameters for the destructor. 2. The return value from pop_back (if any) is nerver handled. 3. The destructor will create a stack overflow. 4. The destructor will create dangling pointers. 5.The destructor will create memory leaks. 6.The destructor will create undefined behavior (equivalent to zero pointer exception). 7.The condition must be: i <size () - 1 8. There is at least one problem with the destructor, but none of the above.
