Now in this case, it's clear that I'm not only saying this function takes an input, I also have to give that input a name.

在这种情况，很清楚的,我不只是说明这个函数有一个输入，我还要给那个输入一个名字。

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。

As I said, what we want to do is, we want to count the number of basic steps it takes to compute a computation as a function of input size.

我刚才提到了，我们要建立，一个根据输入大小的方法来计算,一个计算过程需要的时间,建立这个方法需要几步呢？

It then should take an argument or parameter if you want your function to take input.

然后它必须携带一个参数或参量,如果你想要你的函数获得一个输入。

And yet notice that the function itself, it takes no input.

请注意函数本身，它没有输入。

The answer is I can't. OK, in the simple case of integers I can, but in the case of something more complex like faces or fingerprints or passwords for that matter, it's hard to design a hash function that has completely even distribution, meaning that it takes any input into exactly one output spot.

答案是我不能，好吧,在简单的整数的例子中,我可以做到，但是在一些更复杂的场景中,比如面部，指纹，密码相关的问题中，很难设计一个哈希函数具备完全平均的分配,也就是说，做到对任一输入，可以准确地得到相应的唯一输出,因此在一个哈希问题中。

That in many cases, I can gain efficiency if I'm willing to give up space. Having said that though, there may still be a problem, or there ought to be a problem that may be bugging you slightly, which is how do I guarantee that my hash function takes any input into exactly one spot in the storage space?

普遍存在的增益和权衡,在许多的例子中,可以通过牺牲空间而得到效率方面的增加,话说回来，仍然存在一个问题,或者应该会有一个问题困扰着你,就是我如何保证我的哈希函数能够准确将,任一输入映射到相应的唯一的存贮空间中去？

So before we use printf, a function, and we passed in one input and input henceforth we're gonna call arguments or parameters.

我们在使用printf函数时,先放进去一个输入，之后的输入我们就要,调用参数了。

I'm doing a little trick by the way, I'm using raw input in my function here as a just a way to stop the display.

顺便说下在这儿我有个小恶作剧，在这个函数中,我使用了raw，input方法。

X So here I'm declaring another variable called X, and this is totally legitimate because I already know that if I'm implementing a function like swap or increment, I can absolutely take input.

这里我声明另一个变量，这个完全是合法的因为我已经知道,如果我执行一个像swap，或，increment的函数，我完全可以携带输入。
