When I started merging, I did merging three times across this whole board, this level, this level, and this level, and each time because of the way I was advancing my fingers I touched each number just once.
在整个过程中,我一共做了,三次合并,这一层,这一层,和这一层,而且每次,由于要前移手指,因此对每个数字,仅仅移动了一次。
So, there's more detail on your syllabus -- a detail of what we'll cover every day, but these are the kind of basic things that were covering, and you don't need to write this down, you'll become familiar with it as the semester goes on.
这在你们的教学大纲上写得更详细-,包括我们每次上课的内容,这些东西都是我们会遇到的最基本的问题,你们现在不需要记,在这个学期中,你们会慢慢熟悉起来。
Obviously-- and that's a bad way of saying it, I said constant the previous time-- in the linear case, it's subtract by certain amount.
这么描述很不准确,我之前在,线性算法中也说了常数,它是每次减少固定的量。

And in the group of poems that were assigned for a section last week, you saw Milton alluding to just this passage, although you might not have known it, in Revelation 14 whenever he would speak of the music of the spheres.
上周规定阅读的那些诗歌中,你们看到弥尔顿暗指了这一段,虽然你们可能不知道,在《启示录》第14章,每次他讲到天体音乐时。
Well, for the answer to that we have to go back to ancient Greek music theory, and when you read about this--it's really turgid stuff-- but believe it or not, I teach a course on this at the graduate level.
这个,要回答那个问题,恐怕要追溯到古希腊的音乐理论,每次读这些都会云山雾罩的,不管你信不信,我曾在研究生中开过这个课程
I go to B.B. King's all the time. And sit there, listen to the jazz.

But it turns out that because the Standard I/O Library is -lstdio so common they don't force people to type this all day long because it's just so commonly used.
由于大家都会用到标准输入输出库,因此我们不要求每次都在后面添上,可以省略。
Every time I use it, I'm creating a new instance, that's a different thing inside of memory.
我每次调用它,我就新建了一个类,这在内存中是个不同的事情。
Right? If that was the case in that code, then my complexity is no longer log, because I need linear access for each time I've got to go to the list, and it's going to Lisp be much worse than that.
这里的复杂度不再是对数的了,因为每次在列表中,查找需要线性访问,可能还要糟糕,其实,有些编程语言,如。
Every time you see a square bracket, put a paren in. All right?
每次你看到一个方括弧,你就得在此添加一个圆括弧,明白了吗?
I just doubled the indentation each time so you can see it. So each successive call, notice what's happening. The argument is getting reduced. And we're going another level in. When we get down to this point, we're calling it with just a string of length one.
因此每次成功调用注意它的过程,我们的命题不断简化,而且我们不断深入嵌套,当我们走到这一步的时候,我们就是在调用它处理,仅有一个元素的字符串了。
So I think that's enough, you can follow along with the syllabus and see sort of what the topics are each week, what the reading assignment is to do before the lecture in order to get the most out of the lecture.
我觉得说的差不多了,你们可以根据课程大纲,来看每周会将什么内容,在每次课之前看看阅读任务是什么,这样才能在课上有更多收获
So, for the most part any time we talk about or draw pointers an arrow suffices, which really 71 in there is a number like 71, which is the literal byte that the F is actually in in RAM, but frankly who cares?
所以,每次我们讨论,或者用箭头表示指针,在指针里面有一个数字,如,那是F在RAM中的字节,但是谁在乎它呢?
The loop invariant what does the loop invariant mean? It says, here is a property that is true of this structure every time through the loop.
循环不变量是什么意思?,它是一个在结构体中,每次循环都为真的属性。
And I guarantee you if you do those three things throughout the course that you'll do well in the course and I've said this almost every time I've given the course and nobody has ever told me that I'm wrong.
如果你们做到了这三点,我保证你们会在这门课中取得好成绩,每次开课前我都会这么给学生说,从来没有人告诉我这个说法有问题
And this is useful because if you're actually writing a program that's interactive or that you want to change overtime much like you would a game, hopefully, the game is not going to have the bad guys, for instance, always standing in the same place or the rocks or whatever it is falling from the sky in the same place 'cause it would very quickly become a very tedious game.
这是很有用的,因为如果,写一个交互的程序或者,希望每次游戏都不一样,我们希望,游戏中的坏人物,别老是站在同一个地方或者同一块石头上,或者从天空中同样的位置落下,因为这立刻会使游戏变得乏味。
And now we get the p orbitals, remember we want to fill up 1 orbital at a time before we double up, so we'll put one in the 2 p x, then one in the 2 p z, and then one in the 2 p y.
我们到了p轨道,记住在双倍填充之前,我们想要每次填充至一个轨道,所以我们在2px填充一个然后2pz填充一个,然后2py填充一个。
Well, int is almost always 32 bits at least so far as we've seen so, in fact, any time I draw a pointer hence force I'm just going to draw a square as well because they are, in fact, the same size usually in memory.
嗯,int几乎总是32位的,至少我们至今所看到的是这样的,每次我用一个正方形表示一个指针,因为实际上他们,在内存中的大小是一样的。
And in this case, we go from 8 to 4 to 2 to 1 three times and then on each iteration of this algorithm, each pass across the board I'm touching N numbers, so that means I'm doing N things, log N times.
在这个例子中,我们从8得到4,到2,再到1,是3次,在这个算法的每次迭代中,每一趟我都会操作N个数,也就是所我每次要做N步操作,一共要做,log,N,次。
I think most and you are familiar with the Aufbau or the building up principle, you probably have seen it quite a bit in high school, and this is the idea that we're filling up our energy states, again, which depend on both n and l, one electron at a time starting with that lowest energy and then working our way up into higher and higher orbitals.
我认为你们大多数熟悉奥弗堡,或者构建原理,你们可能,在高中见过它,又一次,这是我们填充能级的观点,与n和l有关,一个电子每次从,最低的能级开始,然后以我们的方式上升到,更高更高的轨道。
I'm walking along the list once, taking two things and saying, make sure the biggest one is next.
我遍历一次列表,每次取两个值,确认最大的元素在后面一个。
