Actually it's not 40, I think these are, 75 alright. So the answer is 75 and the number of calls is 1.7 million.

实际上不是4，我觉得，好了，所以答案是5,调用次数是1百70万次。

It got 85. Same answer, but 50 calls instead of 85.

答案还是85但是只调用了，50次而非85次。

Second thing we've got to worry about is, what's a basic step? All right, if I bury a whole lot of computation inside of something, I can say, wow, this program, you know, runs in one step. Unfortunately, that one step calls the Oracle at Delphi and gets an answer back. Maybe not quite what you want.

我们需要担心的第二件事情就是，什么该作为一个基本的步骤呢？,如果我把一大堆的计算过程放到里面，我可以说，噢，这个程序你知道的，一步就完成了，不幸的是,这一步可能要靠预言家才能得到答案,这可能跟你想要的结果不太相同吧。
