public static int[] BucketSort(int[] array, int numBuckets){

//TODO: implement bucket sort as described at any of the following links:

//http://www.personal.kent.edu/~rmuhamma/Algorithms/MyAlgorithms/Sorting/bucketSort.htm

//http://www.geeksforgeeks.org/bucket-sort-2/

//https://en.wikipedia.org/wiki/Bucket_sort

//Your BucketSort should create an array of size numBuckets, with each of these buckets

//able to hold any number of integers. For example, each bucket could be an ArrayList of

//integers. Rather than inserting in the bucket in sorted order, you can fill these buckets

//and then use Collections.sort() on each ArrayList, similar to how Arrays.sort() works.
