Notice by the way, there's that nice speck true going on saying put a string here.

在这里说放一个字符串在这儿有点小问题,如果是回文的话那么它将会返回真值。

There's the base case. If it's longer than one, what do I want to do? Well I'd like to check the two end points to see are they the same character? And if they are, then oh, I just need to know is everything else in the middle a palindrome?

如果只有一个元素也是回文，这是基本事件,如果比一个长的话那么我应该怎么做？,我将会查看两头是否相同？,如果是的,我只要知道中间剩下的部分是不是回文即可？

And one is the third element. And just return, it's done. It is a palindrome. That make sense.
