After thinking about it, Wang Shang didn't find any more reasonable way, so he could only bring everyone into his own rhythm first. Pen % fun % Pavilion www.biquge.info

But before Wang Shang spoke, Sun Siwen spoke first.

"Do any of you remember that key name? I can only remember the gender male, because at the beginning there were exactly 4 men and 4 women in a staggered arrangement of 8 people, and then there was one less male, and I don't know anything else. ”

It was this sentence that inspired Wang Shang.

"That...... Do you think we can speculate on what this person is doing based on the information available? Wang Shang said.

"Speculation? Do you mean that you are missing a piece of information and extrapolating the missing part based on the result, as in the case of the Olympiad problem? Zhao Zhiao asked suspiciously.

"Pretty much...... I think it's possible to speculate on our current conditions. Wang Shang nodded, "But first......

In order to prevent the current information from disappearing again, Wang Shang took out his mobile phone and took a photo of the computer screen.

Then everyone said goodbye to Director Zhang, went to the cafeteria to find a corner where no one was and began to study.

Because it's not a restaurant, there's no one in the cafeteria, so it's just right to discuss such a secret thing.

"The information we have now is that this list has a total of seven people, 3 men and 4 women." Wang Shang put his phone on the table.

"At that time, it was 4 men and 4 women, so I remember it clearly, and now there are only 3 men and 4 women left, so the name that disappeared should be male." Sun Siwen added.

"At that time, we were proposing that the screening criteria were on-campus staff, people working all night shifts or midnight shifts." Zhao Zhiao also recalled the situation at that time.

Wang Shang nodded and integrated the information: "There is one man missing from the list, and this man is on the night shift...... It's hard to draw any useful conclusions. ”

"That's true...... The only thing I know is gender, but this person is either male or female, and it's useless to figure it out. Zhao Zhiao said helplessly.

"Hey! That's not necessarily, there is still Hideyoshi's gender in the world, don't tell me you don't know! Sun Siwen grasped the key point in Zhao Zhiao's words and made a joke.

Although Wang Shang heard it, he didn't say it, just silently studied the list on the phone.

"You say...... How is this list arranged? After Wang Shang looked at it for a while, he began to induce the two to enter the reasoning mode.

"In what way? Normally, it's in alphabetical order of the name, but ...... This first surname is Wang, and the second one is indeed Du, which doesn't seem right. Zhao Zhiao looked at the list and was a little puzzled.

Wang's beginning pinyin is w, and Du's beginning pinyin is d, if it is arranged in pinyin order, then Du should be in front, but now it is the other way around.

If it's the other way around, the third person is surnamed Cao, and it's obviously not in pinyin order.

"Is that in order of age? You see that the first three people are 52, 47, and 43, which should be in decreasing order. Sun Siwen put forward an opinion.

"So Miss, how do you explain that the fifth is 51 years old? You don't even need to look at this kind of numbers at a glance! Zhao Zhiao obviously found something wrong.

Sun Siwen just stuck out her tongue when she heard this, but did not refute it.

"You say, is it possible that it has something to do with the conditions we screened?" Wang Shang had to open his mouth to remind.

"Filters? You mean working hours, right? Aren't all the people we screen for the night shift? Zhao Zhiao asked strangely.

"No...... No, because this list does not have the function of directly filtering morning and evening shifts, the filter condition we set at that time was: people who had a shift after 18:00, so this list should be sorted by time! ”

Sun Siwen noticed this and successfully found the way the list was sorted.

Zhao Zhiao looked down at the time of the list, and sure enough, the time when everyone's shift started was the basis for the sorting of this list, and everyone's shift time was in the order from morning to night.

"But...... So we can't speculate on anything. Zhao Zhiao was still puzzled.

It's here, Wang Shang can't help but continue to speak, anyway, this girl Wang Shang's setting is that she has a strong reasoning ability, as long as she doesn't mix things about memory in her reasoning, it won't cause suspicion.

"Well...... This is only the first basis for sorting, and the arrangement of computers is generally more than this basis, for example, people with the same shift time, it should be arranged in other orders, otherwise it will all become tied. ”

There was a slight pause: "In fact, among these people with the same shift, this cleaner is ranked the highest, and the duty room is at the end, obviously because B is at the beginning, and Z is at the end, in this order. ”

"In other words, when the same time is at the start of the shift, the list will be sorted from A to Z according to the first letter of the name of the place where the person works."

And then...... The president said before that when there were eight people on this list, men and women were staggered, so he remembered it very clearly, and now ......"

Sun Siwen understood when she heard Wang Shang say this, and immediately interjected: "In other words, the 6th and 7th genders are both female, and there is one less person in between, so the deleted person should be here." ”

"Yes, that's it." Wang Shang nodded, "And more importantly, after knowing this guy's ranking, we can know where he works, as well as his shift time." ”

"What do you mean?"

"Yes, because the first order is the working hours, and the second order is the work location, we can easily get the following information."

"First, because the 6th aunt starts the shift at 18 o'clock, and the 7th aunt starts the shift at 19 o'clock, so we can easily guess that the start time of this person's duty is between 18 and 19 hours."

"Secondly, the 6th and 7th places of work are both the word 'duty room', that is, they both start with the letter 'z', so the person sandwiched in the middle should also work in the duty room."

"With that in mind, we can get the details of this person."

"Male, working in the duty room, between 18 and 19 o'clock, I used to do my best to transfer personnel around the week when the piano sound disappeared and stopped working at the school......"

"In other words......" Sun Siwen asked.

"In other words, we can use this information now to go directly to that duty room to find out!" (To be continued.) )
