So, for example, down here I wrote that it was n 2 and that it was h 2, but when I re-wrote the molecules up here, you saw that it's an h h single bond where it's a nitrogen-nitrogen triple bond.
比如,在这下面我写的是氮分子2,而这个是氢分子,但我在上面把这些分子的形式改写了,大家可以看到,这是一个氢与氢之间的单键,含一个氮与氮之间的三键。
Boy, there's a dumb question, because I've been telling you n log n for the last two lectures the complexity is n log n, but let's see if it really is.
孩子们,这是一个愚蠢的问题,因为前两节课的时候我就已经告诉你们了,复杂度是,但是让我们来看一下是不是真的是这样。
So int n just gives me four bytes for an int, but it doesn't put anything there yet.
所以int,n只是给我们分配了4个字节,但是它没有放任何东西在那里。
It's much better--the uncertainty about x/n is much lower for the case n = 100 than it was for the case n = 1, but it's still there.
当n=100时,x/n的不确定性,比n=1时要小得多,但是不确定性仍然是存在的
