随机打乱数组元素

Posted 2020-08-21

把数组内的元素随机打乱，重新进行排列

 

 

 C#版：

 1 public  static void Shuffle<T>(T[] array)
 2     {
 3         Random random = new Random();
 4   
 5         for (int i = 0; i < 10; i++)
 6         {
 7             int idx = random.Next(i, 10);
 8   
 9             //swap elements
10             T tmp = array[i];
11             array[i] = array[idx];
12             array[idx] = tmp;
13         } 
14     }
