The removeFirst method of the SinglyLinkedList class includes a special case to reset the tail field to null when deleting the last node of a list (see lines 51 and 52 of Code Fragment 3.15). What are the consequences if we were to remove those two lines from the code? Explain why the class would or would not work with such a modification.
