闲着没事，写个冒泡排序玩玩（倒序，从大到小排列）

 1         public int[] GetPoPo(params int[] ints)
 2         {
 3             //长度
 4             int leng = ints.Length;
 5             //交换标志
 6             bool exchange ;
 7             //最多排序n-1次
 8             for (int n = 1; n < leng; n++)
 9             {
10                 exchange = false;
11                 //从水底把泡浮到水面
12                 for (int i = leng-1; i > 0; i--)
13                 {
14                     //如果是个泡泡
15                     if (ints[i] > ints[i - 1])//如果要顺序排序，改为：ints[i] < ints[i - 1]
16                     {
17                         int nonce = ints[i - 1];
18                         ints[i - 1] = ints[i];
19                         ints[i] = nonce;
20                         //标记浮过了
21                         exchange = true;
22                     }
23                 }
24                 //如果没有泡泡浮了，提前跳出循环
25                 if (!exchange) break;
26             }
27             return ints;
28         }
