Recursive Solution

Node * reverse( Node * ptr , Node * previous)
{
    Node * temp;
    if(ptr->next == NULL) {
        ptr->next = previous;
        return ptr;
    } else {
        temp = reverse(ptr->next, ptr);
        ptr->next = previous;
        return temp;
    }
}
reversedHead = reverse(head, NULL);
