实现算法是一件巧妙的事。

Implementing an algorithm is tricky business.

实现算法分类一个阵列。你为什么挑你做的方法？

Implement an algorithm to sort an array. Why did you pick the method you did?

实现算法分类一个链表。你为什么挑你做的方法？

Implement an algorithm to sort a linked list. Why did you pick the method you did?

And the obvious question I could start with is, and suppose I ask you, how long does the algorithm implemented by this program take to run?

我开始这个话题的第一个问题是，假设我问你，由这个算法实现的程序大概,要运行多久才能给出答案？

So, the curious thing about recursion is that pretty much always can you implement this idea of doing the same thing again and again and again but with smaller bytes each time.

可见，递归算法中新奇的一点是,为了实现一个想法,你可以一遍又一遍地做相同的事情,但每次的规模都会有所减小。

Because if you did what I suggested with the list, the time to look up the key would be linear in the length of the list. You'd have to look at each element until you found the key.

字典是用一种很神奇的，叫做散列法的算法,来实现的，后面我们将,会学到一点关于。
