7.21作文原题，还是出自上月寂静

The following appeared in a memorandum from the information technology department of
a major advertising firm:
“The more efficient a firm’s employees are, the more profitable that firm will be.
Improvements in a firm’s information technology hardware and software are a proven way
to increase the efficiency of employees who do the majority of their work on computers.
Therefore, if our firm invests in the most powerful and advanced information technology
available, employee productivity will be maximized. This strategy ensures that every dollar
spent on enhanced information technology will help to increase our firm’s profit margins.”

数学两道

DS：有n，r满足n能被10的r次方整除，但不能被10的
r+1次方整除，问r是多少
（1）n能被2的5次方整除，不能被2的6次方整除；
（2）n能被5的5次方整除，不能被5的6次方整除。
好像是这样的吧。。。

一个店主有3个员工，每个员工可以从5个工作日中选一天休息，问三个员工都不同一天休息的话，有多少种排班方法？
