一辆卡车违反交通规则，撞人后逃跑。现场有三人目击事件，但都没有记住车号，只记下车号的一些特征。甲说：牌照的前两位数字是相同的；乙说：牌照的后两位数字是相同的，但与前两位不同； 丙是数学家，他说：四位的车号刚好是一个整数的平方。请根据以上线索求出车号。

*问题分析与算法设计

按照题目的要求造出一个前两位数相同、后两位数相同且相互间又不同的整数，然后判断该整数是否是另一个整数的平方。

*-a truck traffic violation, the young man escaped. Scene three witnesses to the incident, but did not remember running, only to alight in mind, a number of characteristics. A : The first two digits of the license is the same; B : license after two figures is the same, but with two different; Group C was a mathematician, he said : the license plate number four is an integral exactly the square. Please get more clues kept. * Analysis and design algorithm with the subject of a request to create a double-digit same before and after double-digit same but also between different integers, and then judge whether the integer is another integral to the square. *
