Thank you. I mean, I know I sort of said it to you, but you're right. It's logarithmic, right?
但你们是正确的,是对数级的,它有这样的效率是因为他每次能把问题减半?
And the second thing that we talked about is this idea that we want you to in fact learn how to relate a choice you make about a piece of code to what the efficiency is going to be.
关于这个方法第二件事,就是我们实际上希望,你在写代码的时候,能做出优化效率的选择,因为此。
Is this possible? That's what the first law says it's possible; work is heat, and heat is work, and they're the same thing. You can break even 100% maybe. So let's go back and see what work is.
