my stealth fighter

General Pasinkova admired Marikina's expression at this time. This young girl has already understood that there are only two paths waiting for her, life or death. , the gap between people is even greater than the gap between humans and dogs. Most people will die in a last stand even after mobilizing all their fighting spirit and potential. This proves that their potential is not worth mentioning. The country only needs those who can survive A worthy person, a worthy person, Marikina needs to prove that she is such a person.

General Pasinkova stood up and gave way to two officers in white coats, but instead of leaving, she stood behind the camera and watched the test.

Marikina was like a little beast desperately trying to survive, gnashing her teeth, pursing her mouth, and clenching her fists, staring at the two officers without blinking her eyes.

The presence of the camera and General Pasinkova added to the pressure on her. Although the camera could be hidden, although General Pasinkova could temporarily retreat outside, and although the two officers could show Marikina a smile, they There is no intention to change, and no intention to do so. If the test subject cannot even withstand this pressure, it will prove to be a difficult task.

An officer took out a coin from his pocket, not some magic coin, just a very common, very common coin.

"I toss a coin, you guess heads and tails, the head is heads, the flower side is tails." The officer showed the two sides of the coin to Marikina, said this briefly, and immediately flipped the coin into the air with his thumb.

The coin drew a parabola that was almost straight up and down, and quickly rotated around the central axis, and finally fell back into the officer's palm accurately. Knowing how proficient she is with coins, she must have flipped coins countless times, and done this test to countless people.

Marikina froze, she looked at them in disbelief, is this a test?

"Guess quickly, the answer must be given within 10 seconds." The officer urged, "If you exceed the time limit, you will be judged wrong this time."

"Uh... right... no, but... it's right." Marikina said with trembling lips.

"It's time." The officer opened his palms, and the coin was upside down, which was reversed.

There are two counters on the table in front of another officer, one is red and the other is green. She presses the red counter, and the number of the red counter changes from 0 to 1.

Marikina's face turned gray all of a sudden, as if she had fallen from an abyss, and her lips lost their color. She thought she would only guess once, but the officer immediately tossed the coin again, "The second test."

The coin fell accurately into the officer's palm again.

Only then did Marikina realize that there was more than one chance, she took a few breaths and said, "Anyway..."

The officer opened his palms, and it was right.

The number on the red counter changes from 1 to 2.

Immediately afterwards, the coin was tossed for the third time.

……

10 times in a row, Marikina was very confident that she guessed wrong 10 times in a row.

red counter = 10
green counter = 0
She was so ashamed, so nervous and ashamed that she wanted to beat her head. She thought that the two officers and the general would be very disappointed. It was a trivial matter to guess wrong the first time, but when she took a peek, the coin had been tossed for the 10th time.

"Can I ask...how many guesses in total?" She asked anxiously.

"The standard procedure is to start at 1 times. If your correct rate or error rate reaches a certain level before 1 times, it will end early...the 11th answer is timed out."

One officer answers while the other adds 1 to the number on the red counter.

Marikina was dumbfounded, and even temporarily forgot to be nervous.

From 1 times?
Guess the coin 1 times?

This is a simple game with only "positive" or "negative", only "right" and "wrong". If you exclude the possibility that the person responsible for tossing the coin secretly tampered with it, then guessing the coin is the oldest, fairest, and most important game in human history. One of the most effective guessing games, I am afraid that at least half of the people in the world have played the game of guessing coins at least once in their lives, but probably few people have played this game 1 times in their lives.

In theory, as long as the game is played enough times, the correct or wrong rate should be infinitely close to 50%, but how many times is "enough"? Is 1 times enough?
To her consternation, the coin was tossed for the 12th time.

……

After guessing dozens of times like this, Marikina was less right and more wrong.

Anyone can see that she is completely guessing, but isn't this normal?Who is asked to play the game of guessing coins, isn't it all guessing?

Maybe someone's dynamic vision is super good, so good that they can see the coin spinning in the air, but the coin will be briefly blocked by the officer's finger before the coin falls back into the palm of the hand, even if someone can see the coin clearly and try to guess correctly If it is, you have to estimate how many times it will rotate in the last moment-but so what?This is the first in a series of tests. From the second onwards, even with super dynamic vision, you can only stare blankly.

If there were any changes in these dozens of times, it might be that Marikina's mood was slightly less nervous, and she began to try to use her brain.

She tried to see the rotation of the coin with her eyes wide open, and tried to see if the two officers had any hints of small movements. She felt that the guessing riddle might not be true, so she kept guessing foolishly.

General Pasinkova and the two officers both saw her thinking and psychological changes. After all, this is the only way for all testees, no one is an exception. After the initial wild guessing, they will try to find A trick or a back door... But it's futile, because the game is pure guessing, without any off-the-board tricks, and there is nothing in this pure white cubicle except a table and two chairs, a video camera, and two counters. Nothing else, just to prevent the subjects from thinking blindly.

After dozens of times, Marikina's expression turned to despair again. She didn't find any meaningful hints or hints. As for the rotation speed of the coin, she certainly couldn't see clearly.

Despair is a good thing. Only when she is desperate will she abandon her distracting thoughts and focus on guessing pros and cons.

After 100 times, the interval between two coin tosses, that is, the time left for her to guess heads and tails, is shortened from 10 seconds to 5 seconds, because she is already familiar with the process and has no other questions to ask, so there is no problem. Need to waste time.

General Pasinkova was too lazy to wait for the results of the supercomputer, but she didn't feel impatient with such a seemingly extremely boring repeated test, nor did she feel that it was a waste of her precious time, and she kept watching like a log. , the only moving thing is the pupil.

After 500 times, the guessing time was shortened from 5 seconds to 3 seconds, and Marikina's score was 237 times correct and 263 times wrong.

Generally, from this point on, the subject’s psychology will change again and enter a state of complete despair. After that, there are basically only three directions of change. Life and death are up to fate, so do what you love; the second is to go from despair to mania, start to go crazy, and the whole person collapses, trying to escape the cubicle or attack the test personnel, the consequences of which are needless to say; the third is...

Marikina was already on the verge of going crazy and collapsing, but she still forcibly restrained herself. After she found that there was no other trick, she could only focus on the officer's fist holding the coin, as if she wanted to see through the fist. Like a coin.

Until then, she finally completely ignored the camera next to her and General Pasinkova who was on the sidelines. She even turned a blind eye to the two officers and stopped looking at the counter frequently. She only had the fist holding the coin in her eyes. What was held in that fist was not coins, but her destiny.

In her mind, the image of the coin lying in the officer's hand came up, sometimes it was right, sometimes it was wrong-this was of course purely her imagination, her eyes did not see through the officer's fist.

1000th time.

green counter = 558
red counter = 442
Unknowingly, the correct number has quietly surpassed the wrong number. Although the current ratio is about 5.6:4.4, which is only a limited deviation from the theoretical 5:5, it is undeniable that the slope of the curve of the correct number There is a gradual upward trend.

Is this a sudden change of luck for Marikina?

Which child cries every day, which gambling dog loses every day?No matter how unlucky people are, sometimes they will have a lucky day.

General Pasinkova and the two officers remained expressionless, and the current situation was still within the allowable range of error. Some subjects guessed correctly at the beginning, and they were able to guess more than 100 times in the first 90 times. It makes people think that a peerless wizard was born, but it collapsed later. After guessing 1 times, the correct rate returned to about 50%. The body even guesses correctly, but after the number of times is stretched to thousands of times, it is still around 50%, with only a single-digit deviation at most, and maybe Marikina is the same-as long as the number of subjects is large enough, what kind of situations may arise.

"50%" is like a black hole. As long as there are enough times, the subjects who think they have escaped will always be pulled back into the black hole.

3000th time.

Several hours have passed, but the four people in the cubicle seem to have forgotten the time, and have no desire to drink water, eat, or go to the toilet.

green counter = 1821
red counter = 1179
The correct rate exceeds 60%.

60% doesn't seem like much, but the number of correct ones has already exceeded the number of wrong ones by hundreds of times. If this is a gamble, where whoever loses will give the other one yuan, then Marikina has already started to make money steadily, and the other party will sooner or later going bankrupt.
