I need a contract that says, here's what I want in terms of things that you're going to take as input, to begin your part of the drama, here's what you're going to produce at the output, and the details of what they do inside are up to them.

这些作家相互沟通进行工作呢？,我需要一封规格说明书,我需要一份合约，上面列出了我想要你做的事，这些是你要再开始时做的输入,这些是你要的输出,细节工作就取决于它们了。

And its purpose in life is to maybe take input and maybe produce output.

它的唯一目的是可能是获得输入,可能是输出东西。

So one of the things I want you to notice here is that testing and debugging are not the same thing. When we test, we compare an input output pair to a specification.

这里我想大家注意的一件事,就是测试和调试是不同的两件事情,我们测试的时候，我们把输入输出,跟程序的规格说明书对比下。

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。

Someone-- or someone had to implement, had to write a tool called printf that itself takes input between quotes and produces as output some characters on the screen.

需要有人去实现，这个printf函数,以双引号间的信息为输入,输出相应字母到屏幕上。

And conceptually, the idea of cubing a value feels like you could package that up into a little box, a little tool that takes input, a value, and returns output the answer A* so you don't have to constantly do A star, A*A So this program ,at the end of today, is pretty much the same thing.

概念上，算一个值的立方就像是,你可以把一个值打包放在一个小盒子里,一个用来接收输入的工具,一个值，然后返回一个答案,所以你并不需要一直使用，等等。，A，star，，A，，and，so，forth。,这个程序，最后，是一个差不多的东西。
