Let's step through this code snippet.

让我们逐步研究这一代码片段。

youdao

Let's go element by element through this code.

我们来逐个看看这个代码中的元素。

youdao

Listing 19 shows you how this works — it's not as complex as it is a lot of work, so I'll let you walk through this code on your own.

清单19演示了如何做，虽然需要做很多工作，但是并不复杂，所以我把代码留给您自己来看。

youdao

OK. Note, by the way, if I chase through each possible path, like there's some IFs in here, if there's some places to go, at least in this piece of code, every possible path through this code ends in a return. And that's a good programming discipline, to make sure that happens.

注意一下,如果我跟进每一条可能的路径，像是这里的，起码在这段代码中就有很多走向，这段代码中的每一条可能路径,在结尾都会返回一个值,这就是一条很好的编程定律，请确保这样做。
