And if I'm walking down the list, this is probably order of the length of the list s because I'm looking at each element once.
这可能大概就是数组的长度,因为我会遍历数组中的每个元素一次,现在你可能会想,等等,数组已经排好序了。
And I have this, to write it out, this is order the length of the list squared, OK?
我得写下来,这是把列表的长度平方,对么?
This year,the members are required to list the nominated films in the order of the ones they like best.

Hmm. Well, wait a minute. If I want to sort a list, I'll take one element, I've got to look at probably a lot of the other elements in the list in order to decide where it goes. And that suggests it's going to depend on how long the list is.
我会取一个元素,然后去查看列表,来决定要把那个元素放到哪里,这就意味着它依赖于列表的长度,对,这没什么说服力,但是事实上。
The same ten cities stay at the top of the list from year to year, although their order may change slightly.

Basic idea, before I even look at the code, is pretty simple. If I've got a list that is sorted, in let's call it, just in increasing order, and I haven't said what's in the list, could be numbers, could be other things, for now, we're going to just assume they're integers.
我们可以说基本的思想是很简单的,如果我有一个排好序的数组,让我们认为这个数组是递增的吧,我并没说数组里元素是什么,可能是数字,也可能是其他的东西,现在我们假设是integer类型的数字吧,最简单的方式就是这么做了:
I could still do the linear case, which is order n or I could say, look, take the list, let's sort it and then search it. But in that case we said well to sort it was going to take n log n time, assuming I can do that.
我仍然可以做O的线性搜索,或者也可以以这个列表为例,我们先将其进行排序,然后再进行查找,但是在这种情况下,要花费n,log,n的时间去对其进行排序。
