The number on the board is "12 ▍ 324 ▍ 5667 ▍ 72 ▍ 4868 ▍ 6 ▍ 5298 ? ”

Dr. Zhang's eyes were fixed on the "6", the "6" between the fifth and sixth vertical lines!

He knew he must have caught a clue, but he didn't know what it was.

So, he hurriedly greeted Liu Yi: "Hey, who is that...... Look at this! ”

Liu Yi leaned over ......, "What's wrong?" ”

Dr. Zhang looked at the number "6" without blinking, and pointed at it with his finger, as if he was afraid that it would run away with long legs, and said, "...... This number...... It's alone! ”

......

......

"Alone?" Liu Yi frowned and repeated, and almost in the next second, his eyes lit up: "It's the letter ......!" He suddenly shouted.

Dr. Zhang was stunned...... "Letters? ”

"Well...... It's letters! ”

Dr. Zhang was puzzled: "But, haven't you tried it just now, the alphabetical order doesn't work at all, and the algorithm is irregular!" ”

Liu Yi shook his head: "There is no order, and there is no rule...... It's just a number representing a letter...... For example, this "6" stands for the letter "i" or "a"! ”

"Uh......" Dr. Zhang looked confused: "What is this?" How do you feel like you're blind! 6. How is it "i" and "a"? ”

"It's really blind, but for the time being, this should be the most likely speculation, try it and won't lose a piece of meat" Liu Yi said: "Anyway, according to this method, the first 12 is a word composed of two letters, and 324 is a word composed of three letters...... It's just that the letters represented by each number are irregular, that is, ....... We can only extrapolate from this number in reverse......"

Dr. Zhang thought about it for a while, and immediately understood what the other party meant, so he took over the conversation: "That is...... This "6" represents a single letter, and in grammar, the letters that can form a word independently are only "a", that is, the quantifiers "one" and "i", which translate to the letters "I...... Right! ”

Liu Yi nodded in affirmation.

But immediately afterwards, Dr. Zhang raised an objection: "No, according to your method, the number "5667" cannot be explained, and there are no words with two "a" or "i" in the middle!" ”

After hearing this, Liu Yi immediately put on a proud face: "Who said that a number can only represent one meaning, this number is only up to "9" and there are 24 letters!" ”

"It's 26 ......," Dr. Zhang said with a blank face.

"Forehead......" Liu Yiyu plugged for a moment, and quickly diverted the topic: "It doesn't matter how many there are, anyway, 1 to 9 is definitely not enough......

Dr. Chang certainly didn't want to say anything more on this question: "Okay, so what's next?" ”

"Then one number represents two letters! It's like if there is not enough food to eat, then the two of them eat a bowl, if the urinal is not enough, the two of them will urinate a pit, and if the man is not enough, then it will be a husband and two wives, and the clock is not like this! 24 hours a day, but there are only 1 to 12 on the dial! ”

Liu Yi said with a wow, the corners of Dr. Zhang's eyes twitched a few times, and after explaining it like this, he did understand what the other party meant, but these metaphors were really a bit painful......

Without further ado, let's follow Liu Yi's guess and connect the 26 letters end to end like a dial, bend them into a ring, and fold them in half...... You'll get a new permutation with 13 letters.

Looking at the page, you can see that ...... "a" and "n" overlap, "b" and "o" overlap, and so on......

Now, based on the English alphabet, we have derived a new way of using numbers as "words".

And you should be able to guess the meaning of this string of numbers......

......

The first set of numbers is "12...... What are the words that make up two letters?

he ， it ， me ， my ， e ， is ， do ，an ， or ， in ， on ， go ， so ， to ， no

Since it has been assumed that "6" stands for "a", "n", or "i", "v"

So all words with a, n, i, and v can be removed.

Of these words, only two words are often used as the beginning words of interrogative sentences, and can be connected to "? "The end.

Although it is very troublesome, in fact, to put it bluntly, we are used to starting with the words "is" and "do" in everyday conversations......

However, "is" has been removed because of the letter "i", so ...... "12" represents the two letters "do".

According to the folding algorithm, 1=d and q can be deduced; 2=o and b...... 345 can't be counted for the time being, but we can know that the "72" alone represents "t" and "g", so that we know that the word represented by the number "5667" is "5ant", and now as long as you use your brain a little, you can guess that 5 represents and j.

do 3o4 ant to – 3 is y and l, 4 is you and h.

At this moment, this segment has become a simple crossword puzzle.

In fact, this is the most basic "push to decipher".

In times of war, this kind of password is widely used to transmit information between the front line and the front line, generally this kind of password will have a starting password called "thread head", which is the "6" mentioned above, of course, the real password will not use such a simple letter as the "thread head", otherwise it will be deciphered in minutes if it is intercepted by the enemy......

Okay, now everyone has come up with the answer to this "question sentence", right......

Anyway, Dr. Chang has been very quick to come up with what it means

"Would you like to hear a joke?"

He frowned...... Somewhat inexplicably said out loud.

Liu Yi bent down directly and picked up a piece of glass from the ground......

"What are you going to do?" Dr. Zhang asked.

"Answer him!" Liu Yi said as a matter of course.

......

......

Indeed, this is a question, even if you know what the numbers mean, it is still a question, and the real answerers are Liu Yi and Dr. Zhang themselves......

Is it "yes" or "no"

Of course, this answer also has to be answered by numbers

Dr. Zhang thought for a moment and suddenly said, "No...... According to our algorithm, this question can only answer "on", not "yes"! Because there are only y and e in the numbers, but there are no numbers for s! ”

Liu Yi had already walked to the template at this moment, and responded absentmindedly: "Yes, because he didn't write all the numbers, there are 1-9 here, but there is no "0"!" ”

As soon as he finished speaking, Liu Yi raised his arm and said in the string of numbers "? At the back, three numbers were vigorously engraved.

“380”
