说明：  题目：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1.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。请看具体分析：
(Topic: an integer, and after 100 it is a completely square number, plus 168 is a completely square number, excuse me, how much is the number 1. The program analysis: in 100000 less than judgment, the first and the number of 100 after the root, and the count will add 268 again after prescribe, if the results can satisfy the following after root conditions, is the result. Please look at specific analysis: )
