And then, I'm going to skip down a little bit: Though she never again called back any image of the dead man to dress up, pose, talk to and make answer, neither would she lose a new compassion for the cul-de-sac he'd tried to find a way out of, for the enigma his efforts had created.

And this is called photoelectron spectroscopy, and essentially what it is is very similar conceptually to what we were talking about way back in the first couple lectures when we were talking about the photoelectric effect.

这种方法比所谓的横断面研究更加有效,我将在以后的课中,再仔细讨论这个问题,但横断面研究是指,你一次记录下一群人的状况
So this is a nice little search-- sorry, a nice little sort algorithm . And in fact, it's relying on something that we're going to come back to, called the loop invariant.
恩,这是一个很棒的小搜索,抱歉,和很棒的小排序算法,事实上,它依赖于一些我们要回顾的东西,被称作循环不变量。
String is actually not a data type in C. It actually is something called a char star and we'll come back to this before long.
