You might be winded doing it the second way, but when you get to the top and you are at the 60th story your gravitational potential is independent of how you got there.

It eventually outputs a ticket with the right amount, but my God, how many steps does it take for us to get there?

How do you get there? You go to go here, here and these could be busy roads, and so parents don't want to do it because of safety reasons, so you see how--when the country used to be laid out in a grid, like say New York City still is today, then people walk to get to places.

And that's just a way of reminding you that we want to think carefully, but what are the things we're trying to measure when we talk about complexity here? It's both the size of the thing and how often are we going to use it? And there are some trade offs, but I still haven't said how I'm going to get an n log n sorting algorithm, and that's what I want to do today.
这只是在提醒你们我们要仔细的思考问题,但是当我们在讨论复杂性的时候,我们到底要衡量哪些东西?,是列表的大小和对其进行查找的频率吗?,这里面临一些取舍,但是我还没有说明,怎样得到一个n,log,n复杂度的排序算法,并且这是我今天想要讲的内容。
