We started off talking about binary search, and I suggested that this was a log algorithm which it is, which is really kind of nice.

我告诉了你们这是一个对，数级的算法，这是很棒的,我们来一起看看这个算法到底做了什么。

OK. Binary search is perhaps the simplest of the divide and conquer algorithms, and what does that mean? It says, in order to solve a problem, cut it down to a smaller problem and try and solve that one.

好了，二分搜索也许是,最简单的分治算法，这意味着什么？,也就是说，为了解决一个问题,把它切割成小的问题,然后再来一个个解决。
