OK. So. Why did I do it? It's a simple example, I agree, but notice what I just did. It allowed me to highlight, is the code doing the right thing?

这是一个简单的例子，我同意，但是请注意我刚才是怎么做的,我通过它想要强调，代码是做了正确的？

Right, and just to get a sense of this, let's look at a simple little example, so on your hand-out, you'll see I've got a little piece of code that says assuming I've got one of these points, I want to do things with it, for example I might want to add them together.

这些数组中的一个，你怎么能够知道，它是哪种类型的呢？,你怎么知道它是以笛卡尔坐标,表示的还是以极坐标,形式表示的呢？,你没有可以用来区分的东西，你没有说明这种信息,聚集实际上的意义。

The way we're going to model differentiated products is to imagine, just to take a simple example, imagine a city and this city has one long straight road through it.

我们建立差异产品模型的方法,想象一下,举个简单的例子,想象一个被一条直路贯穿的城市

But that merging process only takes N steps, N*log N so that's N times log of N. Now, it's a little tricky to reason through this perhaps the first time, let's just take a very simple example and see if we can do a little sanity check here.

但这个合并过程只需要N步，所以时间复杂度是,第一次对此进行推论可能会有点儿棘手，我们举一个简单的例子,看看我们能否做一些完整性的检查。

Just to see that in a very simple example, again, we don't use such a complicated example as the one we looked at last time, you could imagine a game, a really trivial coordination game, which looked like this .

不妨再举一个例子,我们就不找上一讲那么复杂的案例了,看一下这个简单的协调博弈,如
