God-level Xueba system upgrades 999 seconds

During the discussion of a certain meeting, A, B, C, D, and E are arranged to discuss in front of a round table, and there are five seats marked with numbers 1 to 5 (not necessarily arranged in sequence) beside the round table.

实际讨论时，甲、乙、丙、丁、戊5人均未按顺序坐在1～5号的座椅上，已知：（1）甲坐在1号座椅右边第二张座椅上；（2）乙坐在5号座椅左边第二张座椅上；（3）丙坐在3号座椅左边第一张座椅上；（4）丁坐在2号座椅左边第一张座椅上。

If C is sitting on seat No. 1, which seat is A sitting on?

No matter how you look at it, the questions on this test paper don't look like a math problem!It's more like a derivation question.

However, what Qin Luo is most afraid of is derivation.

After several level upgrades, Qin Luo's derivation ability has reached lv5.
丙坐在1号座椅上，则根据（1）可确定甲的位置，根据（3）可确定3号座椅在丙（即1号）右边的第一张座椅上。

Therefore, if C is sitting on seat No. 1, it can be known that A is sitting on seat No. 4.

At the same time, Tesla in the same examination room looked normal, and there was even a faint smile on the corner of his mouth.

The exam question this time is not number theory, but logic!

This is where his forte lies.

He is confident that he can get full marks on this question.

Hmph, so what if you're awesome?The final champion must be mine!Tesla grabbed the pen on the table and began to write quickly.

Tap the tip of the pen, and the answer is already on the paper.

In just ten minutes, he had already finished answering!
Check again, the perfect answer... The corners of Tesla's mouth rose, and a confident smile appeared on his face.

Qin Luo, I, Tesla, admit that you are awesome in fencing, but in learning, I am stronger than you.

Qin Luo, I have to thank you, it is you who made me sublime into a better self...

"Katz Katz."

At this moment, the strange sound of Katz sounded again.

Tesla raised his head numbly, and then his eyes widened.

what did he seeQin Luo was carefully tearing open the packing box, as if he was afraid that someone would steal his biscuits.

But, who the hell will grab your snacks?Are you full?
Sensing those scorching gazes, Qin Luo's mouth twitched.

He asked himself very quietly, but he was still caught.

a little embarrassing...

"Do you want to eat?" Qin Luo said silently with his lips parted slightly.

"Eat? Eat a hammer!" Tesla's face suddenly changed, and his face was extremely gloomy.

In 10 minutes, he solved a logic problem with a difficulty of 9.9, which was much faster than his usual speed.

don't eat?very good.

"Kats, Katz~" Qin Luo put the last biscuit into his mouth, then raised his right hand: "Teacher, hand in the paper."

"Clap!"

Tesla's right hand suddenly exerted force, and the pen was instantly broken...

His face was pale, but his eyes were full of red.

He's going crazy!

"Bang!" Tesla slapped the table and stood up suddenly from the stool: "Teacher, hand in the paper!"

It is absolutely impossible for him to lose to Qin Luo!

Looking at the time, it was only ten minutes before the exam, but there were already two people who wanted to hand in the exam.

"Classmates, can you save some face for the organizing committee?" Stanley shouted in his heart.
