快速排序

快速排序C#

效率最高的排序中, QuickSort 最常用

public static void Quicksort(IComparable[] elements, int left, int right)
        {
            int i = left, j = right;
            IComparable pivot = elements[(left + right) / 2];
 
            while (i <= j)
            {
                while (elements[i].CompareTo(pivot) < 0)
                {
                    i++;
                }
 
                while (elements[j].CompareTo(pivot) > 0)
                {
                    j--;
                }
 
                if (i <= j)
                {
                    // Swap
                    IComparable tmp = elements[i];
                    elements[i] = elements[j];
                    elements[j] = tmp;
 
                    i++;
                    j--;
                }
            }
 
            // Recursive calls
            if (left < j)
            {
                Quicksort(elements, left, j);
            }
 
            if (i < right)
            {
                Quicksort(elements, i, right);
            }
        }
