We're gonna have a so called a loop, an infinite loop and you actually experience this in the real world.

我们将会做一个循环，一个无限循环，你会在这个,真实世界里体验它。

So this is a nice little search-- sorry, a nice little sort algorithm . And in fact, it's relying on something that we're going to come back to, called the loop invariant.

恩，这是一个很棒的小搜索，抱歉，和很棒的小排序算法，事实上，它依赖于一些我们要回顾的东西,被称作循环不变量。

And we won't wait here one hundred seconds for it to finish, but we're using the loop, we're updating a variable, and we're formatting it in a nice way.

我们将不会再这里等待100秒来等它完成,但是我们使用循环，我们更新一个变量，我们把它排成一个漂亮的格式。

If you're not updating some variable by incrementing it or decrementing it -- if you're not changing anything, presumably the conditions are never going to evaluate to false or the opposite, so you're just going to have an infinite loop, which might be your goal, but odds are it's not.

如果你不通过增加或减少它来改变一些变量,-如果你不改变什么，大概那个条件永远不会变成错误的,或相反的，所以你将得到一个无限循环，那可能是你的目标，但可能也不是。

On line 2, we're gonna induce what's called a loop, so do you wanna go ahead and Philip henceforth you get to stare, stare at the awkwardness.

第二行，我们将介绍什么叫做循环，你想接着往下读吗,飞利浦正盯着你看，略显尴尬。

Then the next thing in the loop, we're going to enter a nested loop and say for every college in the list e, we're going to print the name of the college.

循环中的第二件事，是进入一个嵌套循环,这个嵌套循环将数组中的，大学名字显示出来。

So in a sense, that's a good infinite loop that is as long as you're using the program, it's constantly checking your grammar and spelling, and underlining things, so infinite loops aren't necessarily bad if the objective is actually being met.

因此从这个意义上说，这是个好的无穷循环,只要你开始使用这个软件，它不停的检查你的语法，拼写或者下划线等，通过这种方式达到目标的时候,这样的无穷循环并不总是坏的。

Otherwise the test is always going to be true, we're going to go off here, but this would loop forever if I did that.

否则测试结果就会一直为真，我们需要离开这个测试，否则就会一直执行循环。

They're running through a loop. It's a common way of thinking about problems.

有继承意义的迭代程序了,它们是以循环的模式来运行的。

They're inside that loop-I've got the wrong glasses so I'm going to have to squint- and we've got one test which is a comparison we've got another test which is a multiplication-- sorry, not a test, we've got - another step which is a multiplication- and another step that is a subtraction.

他们在循环里面呢,我带错眼镜了所以不得不斜视-,然后我们这里有一个比较的测试,还有一个乘法的测试,-对不起，不是测试,是另外一个乘法的步骤-,还有一个减法的步骤。

All right. Second question: or maybe a better way of saying this, and the general format you're likely to see here is, a test involving a variable name, which must be initialized outside of the loop, and which interior to the loop gets changed, so that the test is going to change.

好，第二个问题：,换种更好的方式来说吧，你们通常喜欢的,方式是，这个测试涉及到一个变量名字，变量在循环外已经被初始化，然后循环内部会改变这个变量的值，因此测试结果会改变。

Sorry? OK. You're doing the whole thing for me What's the complexity just of this inner loop m How many times do I go through that loop?

就这一块代码的,我执行了多少次这个循环？,次对不对？，here？，Just，this，piece。,我一会儿就会去得到你的答案的？
