For exercises 16 to 19 assume we have a sorted linked list of Integer. The start of the linked list is referenced by values which, of course, is of type LLNode. For example purposes, assume values poiìnts to a list containing 3, 6, 6, 9, 12, 15, 18, 19,19, and 20. You can and should assume the list in question is sorted in nondecreas- ing order. For each of these exercises you should also create a driver application that demonstrates that your new method operates correctly. 7 16. Write a recursive method numEvens (LLNode list) that re- turns how many even numbers are contained in 1ist. For our example list numEvens (values) would return 5 (the even numbers are 6, 6, 12, 18, and 20).

It's number 16 in the textbook. Thank you!

Transcribed Image Text:For exercises 16 to 19 assume we have a sorted linked list of Integer. The start of the
linked list is referenced by values which, of course, is of type LLNode<Integer>.
For example purposes, assume values poiìnts to a list containing 3, 6, 6, 9, 12, 15, 18,
19,19, and 20. You can and should assume the list in question is sorted in nondecreas-
ing order. For each of these exercises you should also create a driver application that
demonstrates that your new method operates correctly.

turns how many even numbers are contained in 1ist. For our example list
numEvens (values) would return 5 (the even numbers are 6, 6, 12, 18, and 20).
