"Crazy Rubik's Cube: The officially recognized world's largest Rubik's Cube is the 17th-order Rubik's Cube, and the Guinness record for the fastest recovery of this order's Rubik's Cube is 3 hours 12 Minutes.

    In addition to the difficulty factor, the 17th-order Rubik's Cube is also famous for its cumbersomeness and difficulty in twisting. Now everyone observes a disturbed 17th-order Rubik's Cube. Players are asked to rely on mathematical imagination and mathematical construction to write down all the steps to restore them. Each person's Rubik's cube recovery is accumulated as the basis for winning." The

    so-called recovery step refers to abstracting specific problems into data and processing geometric problems in algebraic form. Let the coordinates of a small piece of the Rubik's cube be (x, y, z), and record their recovery trajectory.

    For the sake of the rigor of this link, the program team specially invited the development department of "Guanghuan" to make a 17th-order Rubik's Cube restoration verification program for players to verify immediately after writing the steps.

    As soon as the title of the competition was announced, the audience took another breath.

    The Guinness Book of World Records has been moved out. This is the guts borrowed from heaven to have the courage to touch the Guinness Book of Records. Can't get started and try to play it, but also abstract it into a mathematical problem. Is the show "Intellectual Confrontation" trying to go to the rhythm of heaven?

    "Damn it, I thought it was the Shura field after watching the game in the morning, and then look at the present..."

    Only "going up the mountain of knives, going down the frying pan" can describe the tragic situation at the moment.

    Isn't this really embarrassing a group of high school students? The difficulty of this project is almost demonic.

    "The discussion is limited to half an hour, and the answer is one hour." The host announced the start of the competition.

    I saw the students from the two teams discussed for a long time, and after discussing the correct thinking and steps, everyone began to tap the coordinate steps on the clicker.

    The camera was shown to each student. After the captain in H made the draft, he wrote and deleted it. In a second, he suddenly pressed the backspace key all the way to the end, and the steps were completely deleted.

    On the Yude side, Qi Yaguang's forehead was sweating a lot, and only a few lines of coordinates were laid down. At one point she looked so grim as if she wanted to break the clicker.

    Scumbags: "..."

    shivering and feeling the same way.

    As a teacher of Shuao who has led the team for many years, Lao Wang discussed it with the teacher in H.

    They shook their heads, "If you can directly operate the Rubik's Cube, you can update errors in real time, and recovery is only a matter of time. But abstracted into mathematical problems, which involve thousands of steps and no mistakes are allowed, they are not the same level of difficulty. The easiest way to deal with the Rubik's Cube is to design a program."

    But let these students write, write about the year of the monkey and the month of the horse?

    A teacher shook his head and said, "If you can quickly find out the mathematical laws from a large number of calculations, it is not difficult to write the steps." What

    is difficult is that these students can have such a rich and meticulous mathematical imagination?

    Old Wang's face was cloudy and uncertain, and he was silent with worry.

    H has two national team members from last year, one is in information technology and the other is in mathematics. Mathematical and logical are not separated, and the national Olympic members are also about half of the national Olympic members.

    And Yude's best result was only provincial one in the league, one in mathematics and the other in biology...

    In 40 minutes, the Xinao team member in H submitted the answer.

    The programmer submitted the answer to the system to run, and the recovery rate was 36%, which is equivalent to recovering a little more than two sides, and the audience burst into applause. The fans of Yude Middle School were so nervous that their palms were sweating.

    After an hour has passed, all members' answer results need to be submitted.

    In the system operation test, the big screen quickly rolled out the Rubik's Cube recovered in H, and the scores were 36%, 14%, 8%, 28%, 31%, and 26%, for a total of 143%.

    The six chaotic Rubik’s Cubes from Yude Middle School appeared in everyone’s field of vision one after another. Everyone’s hearts were thumping, and they were raised high in the air—

    I saw Yude’s first percentage score flashed on the big screen, 9 %, the restored Rubik's Cube is messy, and the color blocks are almost the same as those that have never been restored.

    Qi Yaguang covered her face, wishing she could dig a hole to bury herself.

    The next few grades are: 13%, 27%, 17%, 32%. At present, the accumulation has reached 98%, a full difference of 45%. The two teams have opened such a big gap, and the strong team is worthy of being a strong team.

    The five figures have been released, and the students who support Yude are both afraid and anxiously awaiting the emergence of the six figures with dim hope.

    But reason tells them it's almost impossible.

    Yude's best score should be the 32% score. Now the difference between Yude and H is nearly ten points higher than the best score in H.

    If you count the scores in the rush-answer session, H is just two points more than Yu De. Yude regretted his defeat...

    If the previous environment was not too exciting, it would not have brought out how desolate the defeat was at the moment.

    Trivia lowered her head in frustration, Du Heng sent a message and asked, "Is the game over, how is it?"

    She just wanted to type: "It's over..."

    Trivia's thumb typed the word "lose" on the keyboard, but Delayed delivery.

    The southern team's game this year was too tragic. Both teams lost to schools in City B. Last year, No. 4 Middle School was able to win one game.

    Under thousands of eyes, the host blinked, "Steady your breathing, steady your heartbeat, let's take a look at the last result of the Yude team, please look at the big screen——"

    The chaotic Rubik's Cube on the big screen It was restored in seconds, and the six faces were rotated one by one, all of the same color, and a terrible data appeared on the screen: "100%."

    Everyone took a breath, and the big "ah" syllable resounded throughout the audience.

    At this moment, Xu Xu covered his mouth, and a tear burst out from his eyes, almost overflowing.

    At this moment, Yu Qingyan's teeth chewing gum suddenly bit her tongue.

    At this moment, Pharaoh unexpectedly turned around to look at the big screen, his eyes widened and his mouth opened in shock.

    The host smiled and said, "Team Yude won this competition with an overwhelming victory. Let us congratulate them!"

    The students of Yude Middle School jumped up excitedly. The joy and shock were passed on to each other:

    "Aaaaaaaaah, we won!"

    "Labor and management can't believe their eyes!" "     Woooooo

    , my tears are worthless!"

, Pharaoh recovered after realizing it: "What? We... won the first place last year?"
