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。
