Lin Yu was slightly in a trance when he heard the crow man's question. This is a very typical "water filling in the swimming pool" problem. From a mathematical perspective, it belongs to the primary school level. Sure enough, No. 8, the 'student' who heard the question, wiped the water drops on his face and said. "The problem of water filling in the swimming pool is simple. Just assume that the time is X!" He said somewhat eagerly. Lin Yu shook his head. No, the difficulty of this question is not the mathematical part. Before he could speak, his girlfriend next to him, the 'doctor' with the ID "April", said helplessly: "But do you know the volume of this room, the speed of water inflow and the speed of water outflow?" No. 8 was a little dumbfounded: "Ah, yes... Examiner, how much are these data? Can't you give a hint? These should fall into the prompt category!" He looked at the crow man eagerly and asked aloud.
The crow man's feathers and hood on his head were also wetted by the water, making him look wet. He looked at No. 8 and said loudly: "Quack, this is not within the scope of 'prompt'." Uncle Tie looked at No. 8, shook his head and said. "I'm afraid what you're asking is the difficulty of this question - how can a math problem that is difficult for elementary school students appear in the death game... This test is our estimation ability." With that said, Uncle Tie had already reached the edge of the room and started wading around the room. Both No. 8 and April were a little confused: "What is this uncle doing all of a sudden?" Before Lin Yu could speak, the little thief girl named "Bu Forget" spoke up: "I think he is using the 'step distance' to measure the length and width of this room... This uncle is wearing a helmet, is he a professional? A 'craftsman' should be good at this kind of thing." Not forgetting to say this, Lin Yu nodded slightly. But when the uncle measured the length and width of the room, Lin Yu was not idle. He walked towards the crow man. "Excuse me, should the final answer be accurate to minutes or seconds - this should be within the scope of the prompt, right?" Lin Yu asked with a smile. The crow man glanced at Lin Yu, shook the water on his body, and said. "Gaga, let me think about it... That's it. Just give me an answer with an error within five minutes." The crow man said, and everyone breathed a sigh of relief. The error must be controlled within five minutes! This means that the estimate does not need to be particularly accurate. Soon, the uncle completed the circle and returned to the crowd. "According to my estimation, this room should be about 9 meters long and 6 meters wide...the floor height..." The uncle stretched his hand toward the ceiling: "Based on this data, the floor height should be about 3 meters."
No. 8 quickly answered: "Then I understand. The 'volume' of this classroom should be about 162 cubic meters." He said and quickly said: "Next, as long as you know the speed of drainage and water discharge, you can calculate it!" No. 8 said, Uncle Tie and April nodded, seeming to start thinking about how to measure water and drainage speed. "If the speed of each water outlet is uniform, we can find a container to catch all the water flowing out of a single water outlet. In this way, the time of each water outlet unit can be calculated based on the time it takes to fill the container. And here There are ten water outlets in total..." April suggested first. But these words were interrupted by Bu Wang. "Don't be so troublesome. Although there is an error of five minutes, the more data you estimate, the greater the error will be in the end..." Not forgetting to look at Uncle Tie, he said, "Uncle, I just want to ask... are you sure the height of this room is 3 meters? Can the error be controlled within 10 centimeters?" Uncle Tie nodded: "Although the height is not easy to measure, according to my experience, the ratio is almost three meters! After working on the construction site for so many years, my eyes are like rulers!" He said with some confidence. Not forgetting the utility knife he took out from his pocket. "My utility knife is a standard length of 15 centimeters." Wuhu walked to the corner and stuck it against the wall. The tip of the knife touched the water and the blade got stuck in the corner. "Then you only need to calculate that the water will completely submerge it." The time it takes for this utility knife... then multiply it by 20, and that’s the approximate time it takes.” Don't forget to say it, and then the timer starts in your mouth. "1, 2, 3..." At this time, Uncle Tie also reacted. "It's a great idea to turn this problem into the speed at which the water level rises... I have a 'pocket watch' here. This is the prop I got. Use this to time it!" He also walked to the wall, took out his pocket watch, and started counting the time. April and No. 8 also understood the intention of not forgetting, and they both showed expressions of admiration. "I see, if this is the case... we can estimate a more accurate time," April murmured, "This is indeed an oversight on my part." No. 8 curled his lips: "I thought it was a math question, but I didn't expect it to be like a brain teaser, making this 'thief' shine." When April heard her boyfriend's sour words, she poked him in the back: "Be careful what you say, don't always talk nonsense to save face!" April's tone was a little unhappy. When No. 8 heard his girlfriend's words, he could only touch his nose in embarrassment and squat down. "At eye level, it might be more accurate. Let me help you see when the water has stopped." Looking at the few people gathered in the corner to observe the speed of the water level rising, Lin Yu felt something was wrong. As "Uncle Tie" said at the beginning, a simple elementary school math problem would not appear in the death game. At first, everyone thought that the difficulty of this problem was "estimating various data". But when all the data was simplified into the simple indicator of "water level", plus the "five minutes" error allowed by the Crow Man...
This problem is too simple! But, what if we think about it from another angle? As No. 8 just said, what if this is not a logic or math problem, but a "brain teaser"? The biggest feature of brain teasers is that there are "traps" in the questions. Moreover, the Crow Man in front of him is obviously not an NPC who mechanically reads out the rules and questions. He should be a being with high intelligence and independent consciousness. It will "judge" which of his own questions and No. 8's questions he can answer. But... It was because of the answer just now that Lin Yu felt that his tone was a little wrong. "Let me think about it", "Then", "That's it" - a "hint" answer, even involving "answer rules", it uses three uncertain and precise tones. The crow man didn't seem to care much about the "error of the answer", just casually said it for five minutes! It's better to say that the crow man didn't tell the "error" at the beginning, which made Lin Yu feel a little strange. Thinking of this, Lin Yu walked towards the crow man again.
