Explanation / Answer

If you have any doubts, please give me comment...

Node structure/class must have Template variable.

template<class T>

void DoublyLinkedList<T>::append(T* data){

Node<T> *ptr = new Node;

ptr->data = data;

Node<T> *toinsert;

if(!first){

first = ptr;

first->previous = first->next->first;

}

else{

if(first->next==first){

ptr->next = ptr->previous = first;

first->next = first->previous = ptr;

}

else{

Node<T> *last = first->previous;

ptr->next = first;

ptr->previous = last;

last->next = ptr;

first->previous = ptr;

}

}

}
