25. Given the definitions of the classes Node and List below, define the member funetion insert_after and the destructor. The member function insert_after passes in the address to a Node (Node pointer) currently in the list and an integer value to be inserted into the list. This funetion should then create a new Node containing this integer value passed in and insert it into the list after the Node whose address is passed in. If the address passed in is 0, then insert the new Node at the front of the List. The insert_after function is a private helper function that will be used within the insert_sorted public member function. You DO NOT need to define the insert_sorted function. The destructor should ensure there are no memory leaks. Notice there are no push_front, push_back or pop_front functions declared or defined for this List class. You may NOT define these or any other member functions, even as private helper functions. struct Node publie: Node nexti int data Node (int val) : next (0), data (val) elass List ( private: Node headi Node tail publiei List () : head (0), tail(0) () -List (): //IMPLEMENT void insert_sorted(int) //DON'T IMPLEMENT private: void insert after (Node , int) //IMPLEMENT

25. Given the definitions of the classes Node and List below, define the member function
insert after and the destructor.
The member function insert after passes in the address to a Node (Node pointer) currently in
the list and an integer value to be inserted into the list. This function should then create a new Node
containing this integer value passed in and insert it into the list after the Node whose address is
passed in. If the address passed in is 0, then insert the new Node at the front of the List.
The insert_after function is a private helper function that will be used within the
insert_sorted public member function. You DO NOT need to define the insert_sorted
function.
The destructor should ensure there are no memory leaks.
Notice there are no push_front, push_back or pop_front functions declared or defined for
this List class. You may NOT define these or any other member functions, even as private helper
functions.
struct Node {
public:
class List {
private:
Node *next;
Node *head;
Node *tail;
int data;
public:
List () : head (0), tail (0) {}
-List (); //IMPLEMENT
void insert sorted (int); //DON'T IMPLEMENT
Node (int val)
: next (0), data (val)
};
private:
void insert after (Node *, int); //IMPLEMENT
};
