Chapter 137: The Problem of "Chickens and Rabbits in the Same Cage".

Genius remembers in a second [Aishang Novel Network biquge.info] to provide you with wonderful novels to read.

"Humph! Isn't Qin Gongzi's words a joke? Although the first subject is only a small subject, it is the imperial examination that I have clearly stipulated, how can you not know it? Could it be that you knew you were going to lose, so you deliberately pretended that you didn't do your best? ”

Cheng Mubai saw Qin Yong's "surprised" look, so he continued to say with a sneer.

"Ugh!"

Hearing his words, Qin Yong was speechless.

That's right, he really wanted to give a "preventive shot" to the possible results later, but he was definitely not afraid of Cheng Mubai, let alone thinking that he would not be able to win!

In fact, in his heart, the only thing that is uncertain now is whether he will be able to understand the problem by then, and as for the final solution, he is not worried at all!

Because, after all, he is also a graduate of a famous university in later generations, no matter how bad it is, can he still lose to the ancients thousands of years ago in mathematics? That's simply not possible!

Therefore, no matter from which point of view, his chances of winning this competition are much greater than Cheng Mubai's, but he didn't expect that Cheng Mubai decided that he would definitely lose, which really made people feel speechless. So, he smiled, and finally said, "Cheng Gongzi, in this competition, the winner or loser has not yet been decided, don't you think it's too early for you to say this?" ”

"Hmph, it's not early, we'll know in a while!"

Cheng Mubai didn't understand the meaning of Qin Yong's words, he just thought that Qin Yong was just bluffing, so he didn't pay attention to it at all. It's just holding his chest high and waiting for Zuo Mingqiu to say the topic.

He has that confidence. As long as Zuo Mingqiu says the question, then he will definitely be able to solve it, because these days, he has been learning a new "arithmetic" method with Zuo Mingqiu, and this "arithmetic" method, according to Zuo Mingqiu, is just looking for a small number of people to make a "real yàn".

Only if the "real yàn" is good, then it will be promoted within the academy. Therefore, Cheng Mubai is very sure that it is impossible for Qin Yong to understand this "arithmetic" method, so the final result must be that he, a person who knows the new "arithmetic" method, will win, as for Qin Yong. As long as he loses this competition in the end, Cheng Mubai will naturally have a chance to "ridicule" him, so there is no need to rush at this time.

"Hey, you say, this 'arithmetic' competition. Who will win? ”

"Hey, that's hard to say! It is said that their Qin and Cheng families are both business giants, and the men in the family must know how many things like 'arithmetic', but I heard that the 'Yongyue Gongzi' has never cared about the family property, otherwise. He didn't have that much time to hang out in the Qinglou, so much so that he had the reputation of being a gentleman! ”

"That's right! This Qin Mingheng. It is enough to be amazed to suddenly change from an unlearned apprentice to a talented man, and it is conceivable that he must have worked extremely hard for this, so it is impossible for him to have time to study what 'arithmetic', so Qin Mingheng will definitely lose in this competition! ”

"That's right! That's right! ”

Seeing that the second competition was about to start, the audience present suddenly had a lot of discussions, and this time, they still thought that Qin Yong's winning chance was relatively small.

This is also ah, because Qin Yong is now a talented man, it is already an unchangeable fact, so they are slowly accepting it in their hearts, but in order to accept such a fact, they have "constructed" such a scene for Qin Yong.

That is, although Qin Yong used to linger in the land of fireworks during the day, but in fact, after he returned to the mansion at night, he would definitely bury his head in hard study, and only in this way could it be explained why he suddenly jumped from a gentleman who didn't learn anything to a talented man.

And in this case, it is impossible for him, and he should not have time to delve into what "counting", otherwise, wouldn't he be too wicked? That's something they couldn't have imagined anyway.

It's just that what they don't know is that in the society of later generations more than a thousand years later, even a six-year-old child cannot only focus on one subject when he goes to school, but several or even a dozen, and under the weight of so many subjects, most students can still cope with freedom. So, in fact, it's not that people like them can't do it, it's that they don't pay attention to the scientific method at all.

*****************************

"Okay, no more superfluous words! There are two questions in this competition. The first of these is a qualification question, and only those who answer this question are eligible to move on to the next question, while the second question is an infinite question, from which you can clearly examine the attainments of both parties in the subject of 'clear calculation'! Well, now, let's get started."

Zuo Mingqiu finally announced on stage.

It's just that his words made Qin Yong a little puzzled, what qualifications are there? And what is an infinite question? In this Great Zhou Dynasty, is there that there are so many different classifications of "mathematics"? If that's the case, then I'm really going to be a tragedy, because I don't understand what it means.

"Huh? This topic seems to be familiar! Great, I should be able to read it! ”

Fortunately, when Qin Yong saw the so-called first "qualification question" posted by Zuo Mingqiu on the stage, a sense of déjà vu flashed in his heart! And what surprised him even more was that the language of that question was not very complicated, so even if he was as ignorant as he was, it could be understood lightly.

"Today there are pheasants and rabbits in the same cage, there are thirty-eight on the top, and ninety-nine feet on the bottom.

This is Zuo Mingqiu's first "qualification question" to Qin Yong and Cheng Mubai, the number of words in the question is really very short, but the meaning is very clear, that is, "There are several chickens and rabbits in the same cage, counting from above, there are 3 or eight heads, counting from below, there are 99 feet." Q: How many chickens and rabbits are in each cage? ”

Pheasant, that is, chicken. However, Qin Yong didn't know what this meant at first, but it didn't prevent him from understanding the topic, and it wasn't until he fully understood the topic that he yelled in his heart, stunned, and felt a little speechless for a while.

This is the problem of 'chickens and rabbits in the same cage'!

Such a small question, for him, naturally there is no difficulty. What surprised him was that this problem, in fact, he had solved it in the modern society hundreds of thousands of years later! It's just that the topic at that time has been completely translated into modern Chinese, so when he first saw this question now, he didn't react for a while, he just felt a sense of déjà vu, but once he fully understood the meaning of the topic, he immediately woke up! Because of this so-called "chickens and rabbits in the same cage" problem, it is too famous in history.

The problem of "chickens and rabbits in the same cage" actually comes from a strange book written in the fourth and fifth centuries called "Sun Tzu's Algorithm". And this "Sun Tzu Algorithm" has always been a compulsory course for talented and famous people of various dynasties to study the subject of "arithmetic", and the historical bifurcation that the Great Zhou Dynasty and Qin Yong are familiar with is probably in the Tang Dynasty in the sixth and seventh centuries, so this "Sun Tzu Algorithm" is naturally circulated in this era!

And Zuo Mingqiu found out the "chickens and rabbits in the same cage" problem from "Sun Tzu's Algorithm" to study Qin Yong and Cheng Mubai, the meaning is already obvious, that is, to study their basic knowledge. Because as long as you have studied the "Sun Tzu Algorithm", then this "chicken and rabbit in the same cage" problem, it is said that it should not be very difficult, because in "Sun Tzu Algorithm", there is the most specific solution, however, the solution is slightly complicated, so what the answerer needs is just time!

Of course, if one of the two people, Qin Yong or Cheng Mubai, has never studied the strange book "Sun Tzu's Algorithm", then basically he can't answer this question at all, so naturally he won't have the opportunity to answer the next question, so this question is called "qualification question".
