Quicksort is developed by the East Ni Huoer a sorting algorithm. In the average case, sort n items to Ο (n log n) comparisons. In the worst case requires Ο (n2) comparisons, but this situation is not common. In fact, often significantly higher than the other quick sort Ο (n log n) algorithm is faster because its internal loop (inner loop) may be in most architectures it be implemented very efficiently.
