These are going to be fairly common-sense definitions, but they're important, and when you get to a problem set, really nailing down what the system is, not more, nor less, in terms of the amount of stuff, that's part of the system, it's going to be often very crucial.

There're also changes of what you can teach, extends what you can teach, because you can get to concept which are really quite sophisticated that you will never teach it at the introductory level, because the math is the least that you can make it quantitatively, because you have a visualization that shows physically what's going on.

So what's the solution?
所以我们的解决方案是什么呢?
I'll let you chase it through, it does work. What I want to look at is, what's the order of growth here?

你们最好的解决方案是什么呢?
I'm given an integer that's a perfect square, and I want to write a little piece of code that's going to find the square root of it. All right so I'm cheating a little, I know it's a perfect square, somebody's given it to me, we'll come back in a second to generalizing it, so what would the steps be that I'd use to walk through it?

So this is kind of a modern show and that is kind of a retro language and it's also as will be one of the takeaways of this course completely irrelevant to what problem you are solving, the fact that this engineer is using--proclaiming to use Visual Basic really is not a compelling part of the story.
这看起来很时髦,像是重新流行的语言,当然,该语言是我们学习这门课程,过程中附带着要学习的,这与解决什么问题无关,事实上,使用VB真的不是,这个故事出彩的地方。
