An idea of abstraction, that idea of specification, is exactly what we want to use inside of our functions.
抽象的概念,规格化的概念,就是我们想要运用到。
All right, so that notion of abstraction and we're going to come back to multiple times -- during the term-- and it's not just abstraction, -- it's the idea of a specification.
现在就试试,这就是抽象的概念,我回过来说,我们将要多次提到这个术语。
You have to pass it as input to another function, as you'll see as possible in problem's Set One specification, but it's ultimately up to you.
你需要把它传给另一个函数当入参,就像你们将,在习题集1中可能看到的,但它最终取决于你。
