推荐答案

我们不做你的功课：这是有原因的。它就是为了让你思考你被告知的事情，并试着理解它。它也在那里，以便您的导师可以识别您身体虚弱的区域，并将更多的注意力集中在补救措施上。这与软件开发没什么关系。



亲自尝试一下，你可能会发现它并不像你想象的那么难！如果您不理解这个问题，那么您需要与您的导师交谈并让他指出正确的方向。

We do not do your homework: it is set for a reason. It is there so that you think about what you have been told, and try to understand it. It is also there so that your tutor can identify areas where you are weak, and focus more attention on remedial action. And this has nothing at all to do with software development.

Try it yourself, you may find it is not as difficult as you think! If you do not understand the question, then you need to talk to your tutor and get him to point you in the right direction.

整个事情毫无意义！

所有这些都是关于主题的：这是关于数学的，但这个网站是关于编程的。

如果这是你的任务，你应该和你的老师谈谈，因为这没有意义。

The whole thing make no sense!
First of all this is out of topic: this thing is about mathematics, but this site is about programming.
If this is your assignment, you should have a talk with your teacher, because it make no sense.

尝试过多方法
