Given the following definitions that we have used in class to represent a doubly-linked, circular List with a dummy-header node that contains data of type "struct Student". typedef struct { char *name; char *major; } Student; typedef struct node { Student *data;    struct node *next; struct node *prev; } Node; typedef struct { Node *header; int size; } LinkedList; LinkedList *roster; Here is a picture of what the Linked List might look like, although you should answer the following question for a general list (ie, that does not necessarily contain 3 data items).     What TYPE of data is the following: *roster Group of answer choices int int * Node Node * Student Student * char char * This is legal code, but it does not match any of the types listed above. This is illegal code, and would produce a syntax error No hand written solution and no image

template <class T> class List; template <class T> class Node{ friend class List<T>; private:  T data;         Node* link; }; template <class T> class List{ public:     List(){first = 0;}     void InsertBack(const T& e);     void Concatenate(List<T>& b); void Reverse(); class Iterator{ …. }; Iterator Begin(); Iterator End(); private:     Node* first; };   I need algorithm , I think it may use iterator to complile.   The question shows on below photo.

Could you help me the following question?   The Node structure is defined as follows (we will use integers for data elements):   public class Node {             public int data;             public Node next;             public Node previous; }   The Double Ended Doubly Linked List (DEDLL) class definition is as follows:   public class DEDLL {             public int currentSize;             public Node head;             public Node tail; }   This design is a modification of the standard linked list. In the standard that we discussed in class, there is only a head node that represents the first node in the list and each node only contains a reference to the next node in the list until the chain of nodes reach null. In this DEDLL, each node also has a reference to the previous node. The DEDLL also contains a reference to the tail of the list that represents the last node in the list.   For example, a DEDLL with 4 elements may have nodes with values 5, 2, 6, and 8 from head to tail. This…

write in c++ Define the 3 bolded functions for the Queue (circular array): class Queue {  private:    double array[10000];    int front, rear, numItems;  public:    Queue() {front = numItems = 0; rear = -1;}    bool isEmpty();    bool isFull();    void enqueue(double d);    int dequeue();    void dequeueMany(int n);  //remove n values from the front    void enqueueMany(double values[], int n); //add n values from the array}; Hints: void dequeueMany(int n) (hint 6 lines of code, no loops, if there are more than n elements in the queue, use math to re-compute front. Otherwise, make the queue empty.  Don’t forget to update numItems. void enqueueMany(int values[], int n) (hint 3 lines of code, use a for loop, call another function, but make sure there’s enough room in the array first!! )
