Cut the problem in half. Cut the problem in half again. And that's a typical characterization of a log algorithm.

是每次除以特定的量,将问题减一半，再减一半,如此，这就是对数算法的典型特性。

A log algorithm typically is one where you cut the size of the problem down by some multiplicative factor.

对数级复杂度的算法就是指,通过一系列常量级步数的操作,可以将问题的规模。

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。
