It literally halves the amount of time it takes to solve that problem but we can actually do better.

它能把解决问题时间的缩短一半,但其实我们能做的更好。

But that's also nice, it lets you see how the recursive thing is simply unwrapping but the complexity in terms of the amount of time it takes is going to be the same.

它让我们看到了，在复杂度依照时间总数来看,没有变化的情况下,递归是怎么一步步的展开的,我欠你一个糖，谢谢。

And you can see it wrapping its way down, cutting in half at each time until it gets there, but it takes a while to find. All right.

但是这也花了一点时间来搜索，好，让我们看看100万，或者1000万是不是在数组里。
