And so frequently what we try and do is, we take a new problem and map it onto an old problem so that we can use an old solution.
我们经常做的一件事就是,我们处理一个新问题时,把它归结为一个老问题,以便我们能采取老的解决方式。
What you're much better at doing is saying how do I take the problem I've got and map it into a class of algorithms about which I know and use the efficiencies of those to try and figure out how to make it work.
当你碰到问题的时候,更好的方法是把遇到的问题映射,到已经设计好的算法中去,并用这些算法来提高效率,来保证问题得到解决。
This by the way is the portrait of the world; It looks a lot like my map of the Ancient Near East, but it's not.
这也就是世界的图景;,就像我画的古代近东的地图,但它不是那样的。

And you'll find in the end that recursion is a feature of a language, it allows you to map some very obvious concepts like the phonebook tearing in half and half and half and half to actual code without it using some arbitrary human contrived framework like a for loop or a while loop which are much more stilted mechanisms.
最后你会发现递归是某种语言的一种特征,你可以用它将一些非常明显的思想,比如将电话簿划分为一半又一半,映射为实际代码,而不必使用那些人为框架,像for循环,while循环之类的,那是很呆板的机制。
