So if I start off with a list of length n, how many times can I divide it by 2, until I get to something no more than two left?
我能够除以多少次2呢?,直到我得到的长度不超过2么?,对数次,对吧?就像刚才那位同学说的那样?
So if on each iteration of merging I'm doing eight things or more generally, N. That then begs the question, how many levels of this tree are there actually?
可见对于合并我需要迭代8次,一般情况下是N,这取决于具体问题,那么在这棵树中一共有多少层呢?
U.N.workers say they are looking for new sites to build camps for the many more expected arrivals.

So if we say that we have a 2 p orbital here, that means that we can have 2 how many different complete orbitals have a 2 for an n, and a p as its l value? three.
如果我们说这里有一个“2p“轨道,那就意味着我们有,多少完全不同的轨道对于n有一个,而且对于l值有一个p?3个。
His followers are now targets of the Ugandan,south Sudanese, CAR,and the U.N.-backed Congolese forces, leading many to question what objective his latest moves could possibly be designed to reach.

You pay every year a fixed amount on your house to the mortgage originator and then after so many-- n is 30 years, typically--you would then have paid it off.
你每年都在你的房子上支付一定数目的偿款,给抵押商然后,数年后,设n是30年,一般来说你已经能偿清贷款了
O Right there, order n. So I have order n operations at each level in the tree. And then how many levels deep am I? Well, that's the divide, right? So how many levels do I have?
在这儿,所以我在树的每个层次都要做O的操作,那个这棵有多少层呢?,这是一个除法,不是吗?
So,if you take number one--but we don't have to go through them all and I assure you we won't--if you take number one, the Ain,a-i-n,it's named after a river; or if you take number two,the Aisne,a-i-s-n-e, it's named after a river; and how many hundreds of thousands of people died along there in World War One or,you take number three,the same thing,Allier.
如果你看第一个省,我向你们保证,我们不用挨个了解,看第一个省,安省,a-i-n,来自一条河的名字,或是第二个埃纳省,a-i-s-n-e,来自于一条河的名字,有成千上万的人在这里死于,第一次世界大战,第三个,阿列省
N Well, here is a list of size N. How many times can you divide a list of size N by 2, right?
这是一个大小为N的列表,将一个大小为,的列表除以2需要几次呢?
How many times you can divide N by 2 before you get down to 1?
在得到1之前需要将N除以2做几次呢?
And we can generalize to figure out, based on any principle quantum number n, how many orbitals we have of the same energy, n and what we can say is that for any shell n, there are n squared degenerate orbitals.
我们可以总结出来,在,主量子数为n的情况下,同一个能量上,有多少个轨道,我们可以说,对任何壳层,有n平方个简并轨道。
