推荐答案

如果您要张贴作业，至少要使其看起来像您自己尝试做某事！

我们不做您的作业:这是有原因的.在这里，您可以考虑自己被告知的内容，并尝试理解它.也可以在那里帮助您的导师识别您的弱点，并将更多的注意力放在补救措施上.

自己尝试，或学习魔语:您想要炸薯条吗?"

If you are going to post your homework, at least try to make it look like you have attempted to do something yourself!

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.

Try it yourself, or learn the Magic Words: "Do you want fries with that?"

期望您的要求的确切代码是汤匙喂食"的要求.相反，请参考同一主题的您先前的问题的答案"，尝试理解概念并尝试自己实现所需的代码.

Expecting exact code of your requirement is demand of "spoon feeding". Instead refer Answers to your earlier Questions on the same topic, Try to understand concepts and try to implement code of your requirement by your own.
