Write a method findRanks in Java that accepts an unsorted array of integers vals, and a starting and ending rank start and end, numbering ranks from 0, and returns an unsorted (any order is acceptable) array containing the lo-th through the hi-th elements, inclusive, of vals.
int findRanks(int vals, int lo, int hi)
For instance, if vals contains 10 elements as shown:
4 2 9 11 9 19 21 14 16 8
then the call findRanks(vals, 2, 5) will return an array containing the 3rd (remember we number from 0) through 6th items in vals (e.g. 8 9 11 9).
