youdao

在编写这些代码时，我的目的是说明常规编程概念，并围绕这些概念来剪裁代码。

In writing this code, my goal has been to illustrate general programming concepts, and I've tailored the code around these concepts.

youdao

You don't have this particular code on your handout, you do have a code that uses the same concept.

在你们的讲义上没有这种代码，你可以看到相同概念的一个代码。
