Chapter 402: Wrong Question
When a contestant stands up during the competition, it means that she has solved the problem in her hand.
The referee will then submit it to the judges, and the big screen will give the judgment result in real time.
However, after the two of them whispered a few words, the referee trotted over to the judges' seats.
The incident happened suddenly and at a distance, no one knew what the referee and judges said.
But everyone saw the judges pinching their chins and shaking their heads desperately after hearing the answer.
Just when everyone was wondering whether he wanted to withdraw from the competition, several judges had already entered the competition venue.
Frank picked up the calculation draft on Lin Siqiao's desk and took another look at the code in the computer.
He was the one who set the questions, so he naturally knew that the question Lin Siqiao was solving now was the final question of this competition and also the most difficult one.
It was precisely because he knew this that Frank found it unbelievable.
The competition does not have any restrictions on whether to solve the problem from front to back or from back to front.
But all contestants know that the questions become more difficult as they go on, and the final ranking is based on the number of questions the contestants solve.
In this case, solving the problem backwards is very risky and no one would choose this approach.
But Lin Siqiao happened to be that accident.
Lin Siqiao also knew that her decision was undoubtedly crazy and irrational, but considering her actual situation, she had to do it.
It was only when Lin Siqiao was doing mock tests a few days before the competition that she realized that no matter how hard she tried, it was still too difficult to maintain high concentration for six hours.
Especially in the last two hours, her brain was like a computer that had crashed and she didn't want to move at all.
At that time, Lin Siqiao knew that out of the six hours of competition time, she actually only had four hours of effective time left.
Lin Siqiao is the only one in her group. If she chooses to start from the beginning like the other contestants, she will not have enough energy to keep up with the big questions at the end.
Instead of doing this, she might as well concentrate on solving the big questions at the end of the competition.
This way, the questions will become easier as you go on, which can be considered as a reward for hard work.
As for whether it could be solved, this was completely beyond Lin Siqiao's consideration.
If she couldn't even solve the last big question, it would only mean that her ability was not good enough, and there was nothing to complain about if she lost.
So the moment he got the question bank, Lin Siqiao decisively switched the order of solving the questions on the computer.
Just as Lin Siqiao expected, when she saw the last big question, she instantly felt what it meant to have her scalp tingling.
Fortunately, she still has plenty of energy now. If she saw this kind of question four hours later, she probably wouldn't even want to look at it.
But even so, Lin Siqiao still spent more than ten minutes reading the questions.
From determining the solution to setting up the virtual framework, it took more than half an hour.
It took an hour for Lin Siqiao to finish typing all the codes.
Considering that there would be a 20-minute time penalty for answering incorrectly, Lin Siqiao did not rush to submit his answer, but instead carefully calculated it on a piece of draft paper.
After this calculation, Lin Siqiao suddenly had a bad feeling, because the final answer did not match the known conditions given in the question at all.
If she submits now, the result will be an error.
But Lin Siqiao went through all his codes from beginning to end several times and found nothing wrong.
She had no choice but to work backwards according to her own code. It was not until Lin Siqiao compared the known conditions with the calculated results that she discovered that some of the known condition values given in the question were missing and the values were incorrect.
Normally, this situation would not occur in competition questions, but one-third of the time had already passed. After reviewing it, Lin Siqiao finally stood up.
After hearing the news, the judges' first reaction was that this was impossible, but after reading all of Lin Siqiao's codes, Frank shook his head.
"She's right. I was careless about this question. There was a missing 'at most' before the known conditions."
"Also, the value of the initialization condition is wrong. It must be 0, otherwise the following will not hold."
After hearing this, the groups of contestants who were closer to Lin Siqiao were dumbfounded.
It was only at this moment that they realized that the person had already solved the last and most important question.
In other words...she had been doing the questions backwards.
However, this is not the most terrifying thing. The terrifying thing is that even when the question is wrong, she can still calculate the missing conditions and correct values.
How embarrassing it is for these top students in the computer science department!
They knew it, but the people in the stands were confused.
A moment later, Frank picked up the microphone and said, "Congratulations, you have passed this test. You can start preparing for the next one."
As he spoke, he also told the contestants about the last big question.
Having said that, is there anything else you don’t understand?
After the senior people of Fang looked at each other, they felt a little uncomfortable.
You should know that they are one of the initiators of this competition, and the champions in previous years were either Cambridge or Oxford.
They originally thought that they could take this opportunity to save face in front of Prince Di and the Chinese ambassador.
As a result, all the limelight was stolen by this Chinese girl.
What shocked them even more was that China, which had seemed to be relatively quiet over the years, had unexpectedly cultivated such an all-round talent!
I don’t know how many people like Lin Siqiao there are in China.
Thinking of this, they could no longer laugh.
In sharp contrast was Dilar. If loud noises were not allowed during the competition, she would have led everyone in the audience to cheer for Lin Siqiao.
It has been a long time since King Di and Queen Di saw their baby daughter smile so happily, and their mood also became much better.
Thinking of this, the couple looked at each other and said a few words to the people next to them.
Lin Siqiao didn't know about Dilar's smile. King Di simply waved his hand and took out some money to sponsor this simulation competition. At this time, she was still concentrating on her second question.
This question was not as difficult as the previous one, but there were too many conditions in the question, and it took Lin Siqiao nearly an hour and a half just to write the code.
The competition time was already halfway through, and Lin Siqiao knew that she might not be able to hold on for another half an hour, so she subconsciously sped up.
In the end, he passed, but Lin Siqiao spent too much time on these two questions and felt like all his brain cells were dying.
Fortunately, the following questions became simpler and simpler. Although Lin Siqiao was extremely exhausted, he could still hold on.
But people in other groups will obviously feel that their brains are not enough.
Like Lin Siqiao, their bodies have all reached their limits. Now, let alone writing code, it takes them a long time to even read the questions.
Just at this moment, Teacher Frank announced that it was time to close the list, which meant that they only had the last hour.
Before the ranking list was closed, all contestants looked at the big screen.
Everyone was surprised to find that the big screen showed a uniform 6 points, which meant that the latecomer had caught up with the score.
But soon, they realized something was wrong.
For her, she had already climbed all the mountains, but their challenge had just begun.
