Cardinality sorting algorithm

of using an MSD is better if the number of bits is more. MSD, in contrast to LSD, is assigned by the high number as the base, but does not merge back into an array immediately after the allocation, but instead creates a "sub-bucket" in each "bucket", assigning the value in each bucket to the "sub-bucket" in terms of the next digit. Once the minimum number of digits has been allocated, it is merged back into a single array.This article address: http://www.cnblogs.com/archimedes/p/radix-sort-algo
