In java, Implement a comparator called CompareCarsByMakeThenDescendingMPG that can

be passed as an argument to the quicksort method from the lecture notes.

CompareCarsByMakeThenDescendingMPG should return a value that will cause quicksort

to sort an array of cars in ascending order by make and, when two cars have the same make, in

descending order by mpg$.$
