Make sure to check all possible cases for the possible sizes of the linked list. Return the first element of the linked list. def remove_last(link): >>> temp = LinkNode ( 5 , LinkNode ( 6 , Link Ode ( 7 ) ) ) >remove_last (temp) 5, 6, None >>> temp = LinkNode ( 5 , LinkNode ( 6 ) ) >remove_last(temp) 5, None >>> temp = LinkNode (5) >>remove_last (temp) 1
