基本语法

:=

Inside a function, the := short assignment statement can be used in place of a var declaration with implicit type.

Outside a function, every statement begins with a keyword (var, func, and so on) and so the := construct is not available.

最长上升公共子序列

• 最长公共子序列（longest common sequence）：
  • 当$a(x) \neq b(y)$ 时，$f(x, y) = \max(f(x-1, y), f(x, y))$
  • 否则：$f(x, y) = f(x-1, y - 1) + 1$
• 最长上升子序列（longest increasing sequence）：
  • 对于$a(i) < a(k)$ ，$i=1,2,…,k-1$时，有$f(k) = max(1, f(i) + 1)$
  • 否则$f(k) = max(f(k), 1)$

句子：

I’ ve got fingers in lots of different pies.

I do like what I do.

I absolutely loved it.

I think in any walk of life, you like some people, you don’t like some people, but I’ m fortunate enough

I was getting paid to learn. I was reading about the news, current events and I was learning about the world while I was getting paid to do it.

I don’t think there are too many people who are like us. Maybe people watching this will be saying, “I hate my job”, but just stick with it, and something will come of it.

Edison Chen Interview

In the initial, I was just a star and a manager told me what to do every day. And one night, i was actually sold - like I was sold to another company. It was very demeaning to me and I felt very helpless. I felt like I was not in control of anything.

One a very important thing is that when I started being an actor or an entertainer in Hong Kong. People would always be making fun of the way i dress. And people would always be making fun of the way that I spoke or the way I stood.

I think hip-pop wasn’t such a big thing in the late nineteenth, early two thousands in Asia.

So at that moment, I was wondering why they wouldn’t understand what it was that we were doing. At the same time, in the American market there is a huge gap of high-quality Chinese products or high-quality Chinese creativity.

So what we wanted to do was to bring the people that we loved and supported so dearly to China, and showcase these people.

But at the same time, being able to work with them and collaborate with them, and exchange creative ideas, so that we can be the same level. That’s the most important point, for us, it was to be recognized by people all around the world, that we are a Chinese band, but we’re fly too.

We are now actually working on some projects with Polo and with Ralph Lauren. I think it’s a sign of the times, you know.

So I really feel like the youths in China really need to open their eyes and realize that the world is within their grasp.

They just need to believe that they can get it.

Belif is something that is lacking with the youths of China.

They always like to watch and enjoy, but they need to work hard and persevere and excel.

I always tell this. In every place of the world, there are rules and regulations, not even in China, in America, in Europe- in everywhere. But in a creative world, there is no rule, there is no limit. The world is yours, your mind can expands anywhere.

So you need to use that freedom in your everyday struggles.

Now, when they watch these hip-pop videos and they see the street culture stuff, they’re kind of like, “Wow, this is so fresh now, i like it.”

Why do you like it? They might not even know why they like it.

It’s because it represents something that they lack, that is to be able to think openly and be like, i can do this, and i will do this.

[We have to] continue to use our voice for the voiceless.

I’ve been thinking a lot about some of the distressing issues that we are facing collectively.

I think at times we feel, or were made to feel, that we champion different causes, but for me, I see commonality.

I think, whether we’re talking about gender inequality or racism or queer rights or indigenous rights or animal rights, we’re talking about the fight against injustice.

We’re talking about the fight against the belief that one nation, one people, one race, one gender or one species has the right to dominate, control and use and exploit another with impunity.

I think that we’ve become very disconnected from the natural world, and many of us, what we’re guilty of is an egocentric worldview — the belief that we’re the center of the universe.

We go into the natural world, and we plunder it for its resources.

We feel entitled to artificially inseminate a cow, and when she gives birth, we steal her baby, even though her cries of anguish are unmistakable. Then, we take her milk, that’s intended for her calf, and we put it in our coffee and our cereal, and I think we fear the idea of personal change because we think that we have to sacrifice something to give something up.

But human beings, at our best, are so inventive and creative and ingenious, and I think that when we use love and compassion as our guiding principles, we can create, develop and implement systems of change that are beneficial to all sentient beings and to the environment.

Now, I have been a scoundrel in my life. I’ve been selfish. I’ve been cruel at times, hard to work with and ungrateful, but so many of you in this room have given me a second chance.

And I think that’s when we’re at our best, when we support each other, not when we cancel each other out for past mistakes, but when we help each other to grow, when we educate each other, when we guide each other toward redemption.

That is the best of humanity.

When he was 17, my brother wrote this lyric. It said,

‘Run to the rescue with love, and peace will follow.’
