说明：  一个整数，它加上100后是一个完全平方数，再加上168又是一个完全平方数，请问该数是多少？ 程序分析：在10万以内判断，先将该数加上100后再开方，再将该数加上268后再开方，如果开方后 　　　　　　的结果满足如下条件，即是结果。
(An integer, with 100 after it is a perfect square, plus 168 is a perfect square, what is the number of how many? Program analysis: to determine in less than 100,000, plus the first 100 and then prescribing the number, then add 268 before the number of prescribing, prescribing the result if the following conditions are met, that is the result.)
