Now, efficiency is obviously an important consideration when you're designing code, although I have to admit, at least for me, I usually want to at least start initially with code that works, and then worry about how I might go back and come up with more efficient implementation.
现在,当你设计程序的时候效率,是不得不考虑的问题,虽然我必须承认,至少对我来说,我是先担心程序能不能运行,再去把它的效率优化的,我喜欢可靠点的东西。
Another way of saying it is, I've actually said, what did I use there, and , It's basically saying there is the first point, there's the second point, add them together and I get that point.
我要去做的是-对不起,再运行一次-好,你可以看到我已经把,这两个点的坐标值加到一块儿了,然后返回了r的值,我会让大家看到我们,实际上得到的是什么,这看起来不错,好,我做了正确的操作。
