编写一个程序求出200----300之间的数，且满足条件：它们三个数字之积是42，三个数字之和是12.

        static void Main(string[] args)
        {
            for (int i = 0; i <= 9; i++)
                for (int j = 0; j <= 9; j++)
                    for (int k = 0; k <= 9; k++)
                    {
                        if ((i * j * k).Equals(42))
                        {
                            if ((i + j + k).Equals(12))
                            {
                                Console.WriteLine("{0}{1}{2}\n", i, j, k);
                                Console.ReadLine();
                            }
                        }
                    }
        }
