Okay. I'm a producer for a record label called B-Boy Records. One of the original labels
好的，我是B-Boy唱片公司的制作人。B-Boy是最早成立的唱片公司之一。
-
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。

Please choose a rhythm for excerpt one you can choose rhythm A which is or you could choose rhythm B So I'm about to play a piece. It's by Chopin.
请选一个和你听到的相符的节奏,你可以选节奏甲,也可以选节奏乙,我现在要弹一段,肖邦的曲子
-
So I took this to the other side and I divided through by 2b and the b here cancels.
通过移项和通分成2b,就可以消去b了
-
Well, A has to get whatever is in B. So now I'm clobbering, as they say, this value here, and at this point in the story, this is not good.
好的，A将获得B中的数据，现在我把这个值删掉，在这个地方,这是不好的。
-
Put the same point the other way around: If I can imagine A without B, then A and B have to be logically distinct things.
把这点推而广之,如果我可以想象A在没有B的情况下存在,那么A和B在逻辑上是相互独立的
-
B "Ok, so I don't care if I don't get a B in the course.
我不在乎成绩是不是。

I quote in here a guy who croaks before this course starts, Jean Bodin, B-O-D-I-N.

-
So, let's just arbitrarily put it between these two in this case here, but actually there's no reason we couldn't also put it between oxygen b and c, so I'm going to draw another structure where we have it here.
那么，让我们任意地将它们放在这两个之间，但实际上我们没有理由,不能把它们放在氧原子，B，与，C，之间，因此我将把另外一个结构画在这里。
-
I go to B.B. King's all the time. And sit there, listen to the jazz.
我几乎每次都去B.B. King的演唱会，就坐在那儿，听着爵士乐曲。
-
If there's no heat flow between the b and c, then I can say all right, a and c were the same temperature.
如果在与之间没有热量流动，那么我就可以说，好吧与处于相同的温度。
-
I suggested that there was a critical response to those issues that was somewhat negative, and I want to sort of remind you of that from W. E. B. Du Bois's review of Black Boy when it came out.
对于负面问题,有个关键评述，大家看一下,关于《黑孩子》的评论。
-
OK. So if I look at this code, first of all I'm calling search, it just has one call, so looks like search is constant, except I don't know what happens inside of b search. So I've got to look at b search.
首先调用一下搜索，就一步调用,看起来搜索是固定的，除非我不知道二分搜索的原理，那我们来看看二分搜索吧,所以让我们看看，第一行打印出来的内容。
-
I want to solve a to the b.
下面我就开始讲这种方法了。
-
It says, if I am in the base case, if b is equal to 1, the answer is just a.
首先解决基本的，如果b等于1的话，那么答案就是a了。
-
OK? You can take a quick look at it, a even with the wrong glasses on, it says if a 1 sorry, b is equal to 1, a I'm just going to return a.
你们可以快速的过一遍，它是这么写的：如果,对不起，是b等于，那么就直接返回。
-
It says, in either case in general, t of b-- and this is where I'm going to abuse notation a little bit but I can basically bound it by t, 12 steps plus t of b over 2.
我可以用一个,比12+t的数代表,这里有点不准确的地方,具体的步数依赖于奇数偶数，但是你们可以看到在两个case中。
-
So I'm done when b minus k equals 1, or k equals b minus 1.
因此b-k=1或k-b=1的时候，我就可以停下来了。
-
t In the b even case, again I'm going to let t of b be the number of steps I want to go through.
如果b为偶数，那么我还是要用,来代表解决这个问题需要的步骤数。
-
Yeah. Actually, I think I want b minus k equal to 1. Right?
对，实际上，当b-k=1的时候就该停下来了对不对？
-
b OK. In this example I'd use b. All right, as b get-- b is the thing that's changing as I go along here, but it could be things like, how many elements are there in a list if the input is a list, could be how many digits are there in a string if the input's a string, it could be the size of the integer as we go along. All right.?
好，在这个例子里我会用，因为b是一直在变的东西,但是也可能是如下情况：,如果输入是数组的话,变化的就是数组的元素数，如果输入是字符串的话,变化的就是字符串的长度，如果是integer的话,可能就是这个数的大小，对不对？
