人力资源经理再次感到失望。最后一位申请人的面试失败了，和之前24位申请人的面试方式一样。"我是不是给了个太难的任务？- 人力资源经理想。"有这样一个数字为5的n次方，求出数字的最后两位数。是的，当然，n可能相当大，而且不能用计算器，但我们需要的是能够思考的人，而不仅仅是按照指令行事的人。"
你能通过IT城的机器视觉公司的面试吗？
The HR manager was disappointed again. The last applicant failed the interview the same way as 24 previous ones. "Do I give such a hard task?" − the HR manager thought. "Just raise number 5 to the power of n and get last two digits of the number. Yes, of course, n can be rather big, and one cannot find the power using a calculator, but we need people who are able to think, not just follow the instructions."
Could you pass the interview in the machine vision company in IT City?
