Algorithm one: Fast sorting algorithm is a sort algorithm developed by Donny Holl. In average, sort n items to be 0 (n log n) times compared. In the worst-case scenario, 0 (N2) comparisons are required, but this is not a common situation. 　　In fact, fast sorting is typically faster than the other 0 (n log n) algorithms because its internal loops (inner Loop) can be implemented efficiently on most architectures. Quick sort using divide-and-conquer method (http://www ...)
