Let me write a function, in fact the literal thing I would do is to say, identify the things that change, give each of them a variable name because I want to refer to them, and then write a function that captures the rest of that computation just with those variable names inside.

让我来写个方法,实际上我的意思是，辨别出变化的东西,然后给它们逐个命名以区分,然后写一个用来计算,这些变量的,包括计算过程的方法。

And remind you that inside of here, I'd better be changing the variable. All right, if that variable that's counting is not changing I'm going to be stuck in an infinite loop, so I ought to that, right, expect somewhere in there, a change of that variable. All right?

我最好改变了计数器的变量值，好，如果计数的变量没有变化的话，我就会被卡在一个无限循环里面,因此我应该【不可闻的声音】,对，在这里的某个地方，改变下计数器的变量，对不对？我要做的最后一件事情就是？
