What should the code look like to insert a new node at the beginning of the linked list?
- ```c++ void insertFirst(int key, int data) { struct node *link = (struct node*) malloc(sizeof(struct node)); link->key = key; link->data = data; link->next = head; head->next = link; }```
- ```c++ void insertFirst(int key, int data) { struct node *link = (struct node*) malloc(sizeof(struct node)); link->key = key; link->data = data; link->next = head; head = link; }``` (correct)
- ```c++ void insertFirst(int key, int data) { struct node *link = (struct node*) malloc(sizeof(struct node)); link->key = key; link->data = data; link->next = head; head = link; head->next = NULL; }```
