In java pls$!!!5$ 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 $3\mathrm{.}15).$ 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.Additionally, enhance the Singly Linked List by writing a method named reverse$(),$ which contains an algorithm for reversing a singly linked list, L$,$ using only a constant amount of additional space.
