So things that are good candidates for divide And conquer are problems where it's easy to figure out how to divide down, and the combination is of little complexity.
因为适合用分治算法解决的问题,最好是能够简单的将问题进行分解,并且合并的过程不是非常的复杂,只要比线性方案要小。
So if I try to apply the same logic, well how can I divide and conquer this problem.
如果我想要用同样的逻辑,那么怎样划分,并解决这个问题呢?
The first step is divide them in half. All right? I'm not sure how to mark it here, remember I need to come back there. I'm not yet done. What do I do?
我不能确定如何,在这里进行标记,记住我会回这里进行讲解,我还没做完呢?
So if I start off with a list of length n, how many times can I divide it by 2, until I get to something no more than two left?
我能够除以多少次2呢?,直到我得到的长度不超过2么?,对数次,对吧?就像刚才那位同学说的那样?
How many times you can divide N by 2 before you get down to 1?
在得到1之前需要将N除以2做几次呢?
