1. 冒泡排序

 public static void bubbleSort(int[] list) {
        for (int i=0;i<list.length-1;i++) {
            for (int j=0;j<list.length-1-i;j++) {
                if (list[j] >list[j+1]) {
                    int tmp = list[j];
                    list[j] = list[j+1];
                    list[j+1] = tmp;
                }

            }
        }

    }
