The strongest city king in history

Chapter 64 Yang Qingxi's Room
The hardware facilities of Longcheng No. [-] High School are top-notch.

The dormitory where the students live is a four-person room. The water dispenser and air conditioner are fully equipped, and the cafeteria also has food from all over the world.

Students are treated well, and teachers are treated even better.

The teacher's apartment building is only two tennis courts away from the student dormitory.

It is said that when they come to teach in Dragon City No. [-] High School, the school will assign each teacher an apartment. This alone makes many teachers want to teach in Dragon City No. [-] High School. After all, an ordinary house In this place of Dragon City, it would cost millions, not to mention a prime location like Dragon City Yigao.

Li Liyan has been appointed as the representative of the new math class. There is no way. In the last midterm exam, Li Liyan's math score was the only one with a perfect score of 150 in the school. It is not a problem to give 200 points for such a simple and subtle solution.

As soon as this remark came out, the mathematics circle of Longcheng Yigao was shocked.

Many teachers in the school in charge of the Olympic competition wanted to recruit Li Liyan, such as Yang Qingxi, the leader of the mathematics competition team.

"Ahem." Li Liyan coughed to cover up his uneasiness.

"What's the matter?" Yang Qingxi was puzzled for a while, and when she realized Li Liyan's gaze, "Pervert!" Even Yang Qingxi couldn't stand Li Liyan's hot eyes.

Yang Qingxi also regretted, what happened to him today, he brought a strange man to his home, no other man has ever been in his home!
"Well, it's just a kid in the first year of high school. It's nothing." Yang Qingxi blamed all this on the fact that Li Liyan was just a student, and he didn't see Li Liyan as a man.

"Come on, just this question in this book, you do it, I'll cook, if you can't do it, don't even think about going home tonight!" Yang Qingxi said this sentence viciously, without realizing that he was There was ambiguity in the words, and he turned and went into the kitchen.

Li Liyan was even more surprised, what's going on, does Teacher Yang Qingxi really want to eat his tender grass!I am still a pure little virgin!

Forget it, let's look at the topic first.

first question:
There are 10000 lights in a corridor, and there is a switch under each light, which is a switching switch. Press it once to turn it on, and press it again to turn it off.All the lights are off now.

Now the first person comes in the corridor, and he presses all the light switches from 1 to 1 when he passes the corridor.

The second person came, and he pressed the switches of lights 2, 2, 4, 6, 8, etc. up to 10.The lights he pressed were all multiples of 10000.

The third person came and pressed the switches of lights 3, 3, 6, 9, etc., and he pressed the lights in multiples of 12.

The fourth person pressed the light switches of 4, 4, 8, 12, and 16, and he pressed the lights in multiples of 20.

And so on, until the 10000th person comes and presses the switch of the 10000th light.

May I ask which lights were last turned on?
After reading the topic, Li Liyan was stunned. This topic was completely different from what he usually read.

Is this really a math problem, but it's not a problem for my brain that has been blessed by luck.Li Liyan directly formed a scene in his mind, passing through the behavior of these 10000 people at one time, and then wrote out the remaining lights that were still on:

After finishing writing, 10 minutes had passed. Li Liyan thought to himself, this so-called Olympic mathematics competition is quite strange. If he learns to use the power of luck to develop his brain, he will probably be smeared and nothing will happen. Understand.

"Ah!" Yang Qingxi's scream suddenly came from the kitchen.

Li Liyan's expression changed, and he rushed to the kitchen immediately.

Seeing Yang Qingxi pinching his right index finger, red blood kept flowing down.

"what happened?"

"I... cut my finger." Yang Qingxi said in pain and a little embarrassment. Just now, he threatened to ask Li Liyan to use his cooking skills, but unexpectedly the cowhide was blown out, exposing the fact that he doesn't cook often!

Li Liyan didn't care, and picked up the finger of Yang Qingxi's right hand. The incision was not too shallow. Li Liyan didn't think much of it, and directly put the finger in his mouth, because his finger was injured when he was a child, and that's how he dealt with it.
