音乐评论家一直将詹姆斯·P·约翰逊定义为伟大的早期爵士钢琴家，20世纪20年代哈林区“跨步”风格的鼻祖，也是重要的蓝调和爵士乐作曲家。

Music critics have consistently defined James P. Johnson as a great early jazz pianist, originator of the 1920's Harlem "stride" style, and an important blues and jazz composer.

And then, if I want to find out if something's there, I do the same thing. But notice now, hash is converting the input into an integer.

然后，我想查找出某些元素是否在列表中,我做同样的事，但是现在注意，哈希是将输入转化成一个整数，所以，其思想是什么？

So, what's the idea? If I know what my hash function does, it maps, in this case characters into a range zero to 256, which is zero to 255, I create a list that long, and I simply mark things.

我知道我的哈希函数做什么,在这个例子中，它将字母，映射成0到255的256个数字，我创建了一个这么长的列表，并且我只是简单的标志这些东西。

You try to design actually I'm going to come back to that in a second. It's like you're trying to use a hash function that spread things out pretty evenly. But the places you store into in those lists may have to themselves have a small list in there, and when you go to check something, you may have to do a linear search through the elements in that list.

你尝试着去设计,实际上过会儿我会回头讲解这个问题,类似于你需要用一个哈希函数,非常平均的将物体分发出去,但是在列表中你数据,映射到的地方可能会有自己的一小段列表，当你回头查找数据的时候,你可能需要在那一小段列表中做线性查找。
