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。

And probably the obvious thing you'll think about is, we'll come up with a clever algorithm. And I want to disabuse you of that notion.

可能你想到的最有效的方法,就是设计一个,聪明点的算法了,这正是我想你们注意到的。

But in general, it's hard to come up with the really clever algorithm.

但是通常来讲，真正巧妙的算法,确实非常难设计。

Notice here that it's different than the binary search case. We're certainly dividing down, but the combination now actually takes some work. I'll have to actually figure out how to put them back together. And that's a general thing you want to keep in mind when you're thinking about designing a divide and conquer kind of algorithm.

一个分治的例子,注这里，与二分查找所不同的地方,我们肯定是分解了,但是合并的过程还是需要一些工作量的,我会详细说明怎样把它们合并在一起的,当你在考虑设计一个分治算法时,这是你要必须记住的最基本的东西。
