/**
 * Sort an array of numbers in-place and in ascending order using bucket sort.
 *
 * Note that the traditional bucket sort algorithm does not work on negative numbers.
 * Thus, the below algorithm is modified such that any negative numbers in the array are converted
 * to positive numbers and sorted separately from the original positive numbers.
 *
 * Time complexity:
 *  - O(n + k) average
 *  - O(n^2) worst case
 *  - where n is the number of array elements and k is the number of buckets
 *
 * Space complexity: O(n*k)
 *
 * @param arr - array of numbers to sort
 * @param posBuckets - (Optional) number of buckets to use when sorting positive array elements
 * @param negBuckets - (Optional) number of buckets to use when sorting negative array elements
