Scientists in a Certain Laboratory Are Working with a Linked

question 7

Multiple Choice

Scientists in a certain laboratory are working with a linked list class that uses recursion to compute its size.The scientists know that an empty list has size 0,so they never ask a linked list to compute its size when the list is empty.Under these circumstances,

• A) the recursive method can become more efficient by eliminating the test for a base case
• B) the recursive method should still handle the base case of an empty list,because it will still occur even though the scientists never ask for the size of an empty list
• C) the recursive method can be modified to use a list of size 1 as the base case
• D) B and C are both correct
