If you've ever been using some program, you did something completely innocuous, pull something down from a menu, click a button, you didn't do anything wrong and yet all of a sudden the thing just starts hanging there or you get a little spinning beach ball or the hour glass or whatever it is.
如果你之前在用一些程序,做一些无伤大雅的事情,拉下一个菜单,点击一个按钮,你没有做任何错误的事情,突然间有东西开始一直运行,或者一个沙滩上的小球旋转,或滴漏或是别的什么。
In fact, it took the same number of steps as it did in the other case, because each time I'm cutting it down by a half.

We know the early example in sort of Golden Age America, but where else did we see a competitive fringe enter when there was a collusive agreement to keep quantities down?

And Jenner, because he was a trained physician, because he knew something about the scientific method, did something that these more ancient healers had not done in the past, was that he wrote down what he did.

I'll let you just grok it but you can see it's basically doing what I did over there. Setting up two indices for the two sub-list,it's just walking down, finding the smallest element, putting it into a new list. When it gets to the end of one of the lists, it skips to the next part, and only one of these two pieces will get called because only one of them is going to have things leftovers.
你们可以大体的浏览一下,但是它们基本就是我在那里所做的事情,为两个子列表设置了两个指针,指针顺着列表走下去,找到最小的元素,把它放入到一个新的列表中去,当它走到一个列表的尾部时,它会跳到下部分去,两部分中只有一个会被执行,因为只有一个会有元素剩余。
