Those are my... those are the only two exceptions for MTV credibility, but everything else, they just need to stop.

It's just that other meanings are available, and since they're not on the same page, those two other meanings coexist painfully and irreducibly at odds, right?
它只是说其它意思也有可能，由于它们不是在同一水平线上，这两种其它意思,痛苦地共存着，同时又不可削减地矛盾着，对吧？
-
If there are less than two elements there I just check one or both of those to see if I'm looking for the right thing.
列表里是否剩余超过两个元素？,是否剩余不足两个元素,这里面我就挑一两项来检查下是否运行正常。

So, I'll just use those two.
我只说下这两个

So there's two firms, just as there was before, and just as there was before--so the players are those two firms, and just as there was last time, they're producing an identical product.

And now maybe...now I've just heard that maybe one of those two recessions wasn't even a classic recession at all So the question is 1890 to 1945 on the one hand, 1983 to the present on the other, does that tell us that ? we've gotten better at government interventions?
那么现在也许。。。就你们刚才所说,其中一次所谓的衰退也许,根本不能算是典型的经济衰退了,那么问题在于，从1890年到1945年，以及1983年至今的经济状况，是否说明,政府对经济的干预是有利的？

Those two examples I just gave you, one had to directly inject a gene containing vector into the pronucleus of a fertilized egg and you don't have that opportunity in adults.
在我刚给出的两个例子里,一个必须得将带有目的基因的载体,直接注射到受精卵的原核中,这在成年人身上行不通

I want to just use it, I shouldn't have to worry about what variables I use inside of it, I have shouldn't have to worry about where that is in the code, I should be able to just abstract it away. And that's what we want to add today, are those two things.
我只是想使用它,我不用考虑我在这段代码中,使用的是什么变量,我完全不用考虑代码的内容,只要抽象就好,我们今天想补充的内容就是这两点。
-
It says, well I'm going to print out first and last just so you can see it, and then I say, gee 2 if last minus first is less than 2, that is, if there's no more than two elements left in the list, then I can just check those two elements and return the answer.
然后它计算了尾点和开始点的差,如果小于2的话,也就是说数组中的元素小于等于，我对这两个元素进行比较,然后返回结果就可以了，否则的话，我们就去寻找中值点，注意它是怎么实现的,首先这个指向一个列表的开头。
-
And if you just look at the numbers, you can see how it cuts in from one side and then the other side as it keeps narrowing that range until it gets down to the place where there are at most two things left, and then it just has to check those two to say whether it's there or not.
你能看到他是如何不断的，从一个大的范围被拦腰劈开,知道最终只剩下两个数字,然后就只需要,比一比就知道结果了,将它同线性查找比较下。
-
Meaning, I'm just going to write a little loop that does that. All right, so let's go back to our code. That's right, let me pull this over a little bit, so I can see it. And what I'd like you to look at, I'm going to highlight it just for a second here, is those two pieces of code.
意思就是我只需,写一个小循环就可以了,让我们回到代码,让我们向下拉一点,我才看得见,我希望你看看这里。
-
So to just preface what we're going to do next time, what would happen if I wanted to do sort, and rather than in sorting the entire list at once, I broke it into pieces, and sorted the pieces, and then just figured out a very efficient way to bring those two pieces and merge them back together again?
所以为了引导下一次,我们要讲的内容,如果我想做排序,而且不是一次吧整个列表排完,会发生什么，我把它拆成小的列表,然后把各个小列表排序,接着用高效的方法再把小的列表？
-
That's just the those-- let me use my pointer that's just these two lines here. I checked the value, and in one case, I'm changing the last to be mid minus 1, which is the case I'm in here and I just call again. All right?
来看看ppt，这里有两条线,我检查了值，在一种情况下,我把last指向了中点减一,就是这种情况,我们再来调用一下怎么样？
