In the discussion of radix sort bucketPass sorted integer values based on a digit of the number. It was important that the sort was stable—that values with similar digits remained in their original relative order. Unfortunately, our implementation used Vectors, and to have bucketPass work in O(n) time, it was important to add and remove values from the end of the Vector. It was also necessary to unload the buckets in reverse order. Is it possible to clean this code up using a Stack or a Queue? One of these two will allow us to unload the buckets into the data array in increasing order. Does this improved version run as quickly (in terms of big-O)?
