快速排序的例子

import java.util.Arrays;

public class QuickSort {

	public static void main(String[] args) {
		int[] array = {72, 6 ,57, 88, 60, 42, 83, 73, 48, 85};
		sort(array, 0, array.length - 1);
		System.out.println(Arrays.toString(array));
	}
	public static void sort(int[] array, int start, int end) {
		if(start > end) return;
		int i = start;
		int j = end;
		int x = array[i];
		while (i < j) {
			while(i < j && array[j] >= x) {
				j--;
			}
			if (i < j) {
				array[i] = array[j];
				i++;
			}
			
			while(i < j && array[i] < x) {
				i++;
			}
			if(i < j) {
				array[j] = array[i];
				j--;
			}
		}
		array[i] = x;
		sort(array, start, i - 1);
		sort(array, j + 1, end);
