And the last two lines are a bit weird, but there you go.

Let me know what you think in the comments below!

应该是理解成诗了……

输入：Batman opens the present. It contains a coupon for new parents, but is expired. This is a Joker joke.
输出：
Batman: I'd like to offer you one of these for your mother.

(Batman opens the present and pulls out the woman from his pocket and hugs her. She immediately runs away as soon as he pulls her back into his arms)

Batman: I can't stand people like you, Joker.

Joker: (to Batman) You can't. You're a coward!

(The Joker leaves)

Batman: (to Alfred) You should stay here with her. She can be of help.

Alfred: Of course.

(Alfred goes into the room)

Batman: Do you want me to call Alfred?

Alfred: No. Not that I'm afraid. I'm afraid of you.

Batman: What is it?

Alfred: I'm afraid of you.

Batman: You're afraid of me?

Alfred: Of you.

(Batman takes off the Joker mask and puts it on)

ff gird 比 chrome 的好太多了

netlify 哪里不好，非要自己搭？

高尔夫啊

瓜子优信收的太高了，比车商高

几个建议：
看李老鼠他们的验车视频，学习验车的几个要点，如何判别火烧水泡碰撞
下载汽车之家二手板块看车型配置价格，再下个查博士，到时候四十六块可以在线查维修保险记录
网上看这个车型的配置，和其他配置有啥不一样，都拿小本本记下来，到时候坐车里挨着看是不是这一个配置
确定两个车型和配置之后，指着这俩车去二手车城找，没有目的跑断腿
去二手车城千万别找中介，直接看车问谁是老板，不让中间商赚差价

同事给了段代码对比尾递归优化：
```
int f(int n, long long t){
if (n == 1) {
return t;
}
return f(n-1, n * t);
}

上面一段没有优化，push callq leave 就一直进栈到最后再一个个出栈
下面的优化过，就是 jne 循环

优化的是栈吧

是这篇文章么，我评论的
我觉得是 O(n)，但是作者说是 O(1)
