推荐答案

我是初学者所以我需要整个代码

它不是那样的工作。

我们不为你工作。

如果你想让别人写你的代码，你需要支付 - 我建议你去Freelancer.com并在那里问。



亲自尝试一下，你可能会发现它并不像你想象的那么难！



如果您遇到特定问题，请询问相关问题，我们会尽力提供帮助。但我们不打算为你做这一切！

"i'm beginner so i need the whole code please"
It doesn't quite work like that.

If you want someone to write your code, you have to pay - I suggest you go to Freelancer.com and ask there.

Try it yourself, you may find it is not as difficult as you think!

If you meet a specific problem, then please ask about that and we will do our best to help. But we aren't going to do it all for you!
