我只是为了避免在返回时一堆的多余的条件判断语句。

I just wanted to avoid a bunch of superfluous conditional statements that the code might have to go through later on.

这两个分支都是简单的语句，他们的位置也可以继续放条件判断语句的。

Those two branches are both simple statements, although they could have been conditional statements as well.

那么，如果不采用默认值，则将要增加相应的判断语句，程序的长度就可能增加60行。

So, if do not use acquiescent value, will add relevant judgement statement, the length of the program increases 60 possibly.

You've got a loop, you've got a condition and a boolean to check if he's touching the edge, and some statements to tell him to shout or to actually turn around.

我们有一个循环，通过一个条件和一个布尔值来判断,是否触到了边缘，还有一些语句,让它回头并咆哮。
