Su Xiaomu in the crowd didn't want to be dazzling at all.

Even if it was Sears' fingered cough, Su Xiaomu didn't really want to continue to be in the limelight.

He is an exchange student from outside, and he does not plan to be an exchange student, so it is not necessary to be overly prominent.

Seeing that Su Xiaomu didn't take the initiative to stand up, Hills didn't say anything.

There is a smile on his face that is neither salty nor light.

If you look closely, you will find that it is a very easy to understand expression of 'watching a good show'.

Although Shears doesn't know much about everyone's algorithms, he is still very confident in the difficulty of the questions he gave.

What's more......

For a limited time.

The first formal class is scheduled for the main class time, which is 1 hour and 35 minutes.

In terms of the opening remarks and the previous in-depth and easy-to-understand words, Sears had already spent about fifty minutes.

Follow the normal process, or the general course of teaching.

At this time, the lecturer or professor will not arrange a very difficult quiz.

Sears, on the other hand, did the opposite.

Approximately, probably, maybe, or just want to see Su Xiaomu's level directly.

Professor Hills is also an ordinary member of the MIT CSAIL lab and heard the name Su Xiaomu from his own channels.

In addition to hearing that Su Xiaomu was different from the average excellent.

Heard too......

Su Xiaomu's handsomeness that is suitable for both Chinese and Western.

That's why I want to make a big scene in the first class.

If the rumors are true, Hills believes that he will soon be able to see Su Xiaomu's excellence.

The twittering discussion began with Louis's words and went deeper.

"The knight's journey through checkers is a classic problem. ”

"If you have enough time, it's perfectly fine, it's a brute-force problem. ”

"Makes sense. ”

"I'll think again. ”

“……”

There are also people with hated expressions on the sidelines.

"What are you talking about? Why don't I understand at all?"

"What's on the projection, and how does it feel like you're playing a game?"

"Dude, connoisseur!"

“……”

In fact, not everyone is so good.

Moreover......

There are no credits, exams, quizzes, or other means to grasp students' learning level in communicative learning.

So some people don't understand and don't plan to understand it.

What's more, for many people, coming to MIT in the United States is worth the ticket price!

Time passed minute by minute, and Su Xiaomu stood silently in the crowd, looking like I was very gregarious.

But not going to take the lead.

Until, someone's eyes slid over Su Xiaomu's body, and they began to make suggestions consciously and purposefully.

"Sue, you're good at algorithms, why don't you give it a try?"

"Yes, yes, this is the first class, and the professor should just want to dig a hole. ”

"We couldn't find a solution for a while. ”

"If you exhaust the method, it's too late to ......"

“……”

Commonly known as......

Catch the ducks on the shelves.

In fact, Su Xiaomu saw everyone's efforts in the crowd.

Some are in a hurry, such as Louis has already written a sample of the writing on A4 paper, and the possible structure of the tree.

I have to say that MIT's students who study hard are really good.

That is, it is now limited and messy.

Anyway, from Su Xiaomu's point of view, if Louis is given a little quiet, undisturbed time, he should be able to successfully solve this algorithm problem.

Su Xiaomu also saw Chen Jiming's attempt.

It's a pity that Chen Jiming's route at the beginning was wrong, and he had to tear it down and start over.

Chen Jiming has realized his mistake and is correcting it.

This kind of classic problem was brushed by Su Xiaomu when he took Chen Jiming and Shang Siyu to team up.

When more and more eyes focused on himself, Su Xiaomu proposed in a small voice in the crowd: "Or ......"

"I'll give it a try......"

Quickly, quickly vacated the space.

Su Xiaomu's surroundings were suddenly ready for Su Xiaomu to show his life.

Su Xiaomu smiled slightly: "I'll try, I may not be able to find the answer quickly." ”

Although he had already been sure, Su Xiaomu was still very modest.

This is a traditional virtue in Chinese culture.

After receiving a few pieces of A4 paper and a pen, Su Xiaomu wrote out examples 1, 2, and 3 according to the question stem unhurriedly under the gaze of the onlookers.

The tree structure is written......

Some discerning people have already read between the lines, like Louis.

Seeing that Su Xiaomu did not stop writing, the onlookers did not beep loudly.

Louis also has no desire to show, and everyone who understands wants to know what Su Xiaomu has to show.

Su Xiaomu hesitated.

Keep writing.

I wrote out the code of a generic C++ program with a pen.

Generally speaking, the code of such an algorithm problem is not very long, and the most may be one or two hundred lines.

Dozens of lines less.

However, in today's world where computers can be used at will, few people can write code by hand.

Some keywords can be completed to save time, not to mention that the code written in the compiler will be more elegant.

Although many girls and children want to see Su Xiaomu continue to write.

Because......

Su Xiaomu's handwriting is also excellent.

Su Xiaomu started very quickly, and said while writing: "There may be more solutions, but for the time being, I have thought of such a plan, which is relatively simple, so I will write it by hand first." ”

This is also the habit of those who have participated in competitions.

On ICPC, most people choose to print the code for a manual attempt after having a problem compiling their code.

Because the total time is limited.

Because the computer is the only one.

Because it is simply handwritten, there are no notes or some explanations.

So the code looks incredibly concise.

There are only 35 lines in total.

It's an odd number.

Not in pairs.

Just when Louis and others were brain-making up the possibility of successful operation of this code, applause suddenly rang out from the corner.

“very very perfect！”

"Sue, I've heard of your name and your excellence, but I really didn't expect you to be so perfect. ”

Professor Shears was amazed.

Then the blue-green eyes rolled, and he said with a smile: "Su, why don't you talk to everyone about this problem." ”

Su Xiaomu: "......"

Hehehe, the routines of the Americans are really deep!

Su Xiaomu didn't know what to say.

Unable to shirk it, Su Xiaomu had to stand on the podium again and explain in standard English unhurriedly:

"The knight's travel algorithm is very classic, generally on an N*M chessboard, a knight is placed in any position, and the knight walks the 'Japanese character', and the question is generally whether the knight can not traverse the board repeatedly. ”

"According to the description of the problem, the chessboard has additional constraints, the knight can never cross his own path, and the path must form a regular hexagon. ”

"In general, there is a general way to solve such problems, exhaustive ......"

"Of course, there are more concise solutions, such as this ......"
