Not surprisingly, the while loop also requires a set of mutable local variables, in this case named a and b, in which to store the current pivots.

毫不令人奇怪的是，while循环也需要一组可变本地变量，在这里，这些变量被命名为a和b，其中存储的是当前支点。

So I take 2 plus 3 b steps to go through this loop OK. So if b is 300, it takes 902 steps.

好，如果b是300的话就是902步,如果b是3000那就有9002步。

b times. So I've got to go 3 b steps. All right I've got to go through the loop b times I've got three steps each time, and then when I pop out of the loop, I've got two more steps. All right I've got the initiation of answer and the return of it.

好，我一共执行了b次循环,每次循环内部进行了三次基本操作,当跳出循环后还有两个基本操作，因此这个初始的答案就是,2+3b次基本操作,来完成这个循环。
