1. A linked list does not need to have a pointer that points to the first node of the list. True or False?

2. A linked list needs to have a pointer to point to the last node of the list. True or False?

3. If "head" is the only pointer that points to the first node of a linked list, to traverse the list, you should move the head pointer to each node one at a time. True or False?

Please explain your reasoning. (C++)
