When you're teaching it you get to call it your Sorry John, you're absolutely right. OK.

你是对的,顺便请你们注意一下。

OK. If last minus first is greater than or equal to 2-- sorry, less than 2, then either look at this thing or look at that thing.

大于等于儿，抱歉，是小于二,看看这里或者那里,这就是我说的要特别小心的地方。

Good question. Actually, I've got to get rid of this candy, so since it was a good question, here you go. Nice catch. Almost. Sorry. OK. No, I'm not. I'm sorry. I thought you had it, and then I've got the wrong glasses on and I realized you didn't, so I will, ah come back to that later.

问得好,事实上我不得不给你这个糖果，因为你问的很好，接好，不错，抱歉，对不起，我以为你接到了，我带错了眼镜而且,我意识到你没带错，所以我会待会再讲。

Sorry? OK. You're doing the whole thing for me What's the complexity just of this inner loop m How many times do I go through that loop?

就这一块代码的,我执行了多少次这个循环？,次对不对？，here？，Just，this，piece。,我一会儿就会去得到你的答案的？

Yes? OK. Sorry. You're going to see why this was a mistake in a little while.

我该这么做，对不对John？,嗯？哦，抱歉，一会儿你们就会看到。

And keep going, until the square of one of those integers is greater than or equal to - sorry, just greater than x. OK, why am I doing that? When I get greater than x, I've gone past the place where I want to be.

如果还是比x小的话，跳到3，这么继续下去,直到一个整数的平方大于或者等于,对不起，是大于x，好,为什么我要这么做呢？,让我得到的整数的平方和。

And if I were to use that again, I'd just put it on your handout, I could go back and rewrite that thing that I had previously for finding the square roots of the perfect squares, just using the FOR loop. OK. What I want to do, though, is go on to-- or, sorry, go back to - my divisor example.

它可以是任意的集合,如果我又要去用这个方法的话,我会把它放在你们的课堂手册上的,我可以回过头去用FOR循环，重新写我们那个求平方数的程序，我想要做的是，是继续-哦抱歉,回到-我的除数那个例子。
