将一个数随机分成N份.net代码示例、java,php及其它语言同理

代码还可以精简，拿去自行琢磨.

//和
            //int sum = 8;
            //份
            //int fen = 48;
            //for(int i=0;i<8;i++)
            //{

            //}
            int a = 8;
            int[] arr = new int[47];
            Random rand = new Random(DateTime.Now.Millisecond);
            for (int i = 0; i < 47; i++)
            {
                arr[i] = rand.Next(a);
            }

            Array.Sort(arr);
            // split数组中存放的就是最后分成10份的数，
            int[] split = new int[48];
            for (int i = 0; i < 48; i++)
            {
                if (i == 0)
                {
                    split[i] = arr[i] - 0;
                }
                else if (i == 47)
                {
                    split[i] = 8 - arr[i - 1];
                }
                else
                {
                    split[i] = arr[i] - arr[i - 1];
                }
            }
            // 这里可以验证和是不是1000
            int sum = 0;
            string sj = "";
            for (int i = 0; i < 48; i++)
            {

                //{
                //    Console.Write(split[i]+",");
                //}
                //else

            Console.Read();
