Scalp numbness is generally an adjective used to describe a person's feeling or state of extreme fear or nervousness.
But it is also a physical clinical phenomenon - when you are stressed, tired, sleep deprived or other diseases, your scalp will feel like there is an electric current.
Ye Ming felt his scalp numb just now.
Not because of nervousness, nor fear - although when this feeling arose, he felt fear.
"What did you just do?!" He stood on the bed and asked in his mind.
"I have achieved a wave-related resonance between dimensional waves and biological currents with you."
"..."
Ye Ming bit his lip and slowly sat down after taking a few deep breaths.
"I need to wake up first."
"Okay, answer me, what is Weibo?"
"have no idea."
"?? Why can you achieve this damn resonance with me, but don't know the principle?"
In my mind, Eta's voice sounded quietly: "The host can communicate with me. Does the host know the principle?"
Ye Ming was stunned.
"Grass!"
Etta: "The use of tone of voice does not mean that you have any inappropriate thoughts about me."
Ye Ming: "...Be serious, do you know what your behavior just means?"
"It means that I can interfere with your biological current in the form of resonance. Although I don't understand the principle of this ability yet, the drawing gives me this ability."
"Yes, but I want to tell you... you can kill me, do you understand?!" Ye Ming looked at the darkness ahead, his eyes flickering.
Being able to interfere with his own bioelectricity at will really frightened him.
No matter how bad his biology is, he still knows that the generation and circulation of bioelectricity are signs of life and the basis for maintaining life.
And Eta can directly "interfere" with his own bioelectricity...
Putting aside the principle, this fact alone was enough to scare him.
"I won't kill you."
"Who knows? Are there still fewer blackened AIs?"
"My logic and mission is to assist you, and the premise of assistance is that you exist as an intelligent life form." Although Etta's voice is still as calm as an AI, Ye Ming always sounds a little sarcastic.
So he thought about it seriously and found that what Eta said was true.
"Okay, let's get this out of the way first. No further interference with me is allowed without my permission or request."
"yes."
"Then let's discuss it again." Ye Ming took a deep breath, and his eyes began to be full of expectation: "Tell me, what's the use of it?"
"Whatever your bioelectricity can achieve, I can do for you with your permission. But the knowledge and fragmented information you have given me so far are not enough to support my in-depth analysis of this issue."
Listening to Eta calmly stating the facts, Ye Ming suddenly fell silent.
No need for Eta to analyze, he knows.
Brain-computer interface is “just”.
…
Four days later.
The triumphant victory of the provincial RC team was treated like a hero.
The school's Youth League Committee and Student Union all showed up, and the school's TV camera kept filming everyone's faces from the moment they got off the plane until everyone took a group photo in front of the school motto stone.
After finishing all this work, Ye Ming returned to the dormitory, changed his clothes, and went straight to the library with his notebook on his back.
In his old position on the third floor, senior Shen Ruhai and Qi Yumo had been waiting for him for a long time.
When Qi and Mo saw him, they pursed their lips and smiled: "Congratulations."
"Repeated congratulations don't count" - Qi and Mo Zao learned about the news of the RC team winning the Southern Competition through the school's official account not long after the game ended four days ago, so they sent a congratulatory message on WeChat and asked for a meal. dinner.
Ye Ming naturally agreed.
Seeing Shen Ruhai and Qi Yumo sitting opposite each other, he hesitated and decided to sit next to Qi Yumo.
What if Senior Shen’s girlfriend comes?
"The school's ACM qualifiers will be held the day after tomorrow, right?" Ye Ming looked at Shen Ruhai while holding his notebook.
Shen Ruhai nodded lightly.
"Then shall we continue to brush up on Likou? Or brush up on Luogu (luogu, a professional ACM question brushing website)?"
"Let's go for Likou. The questions for this test are basically from Likou. The standards are five, three, and two."
Qi Yumo added with a smile: "The reason why the school recommends Likou is entirely because... it may be useful for ACM if you use Likou, but it will definitely be useful for future graduation exemptions."
"Okay, then I'll just choose the topic randomly."
As Ye Ming spoke, he directly opened the Likou website and chose a random question.
Qi Yumo on the side read the question in a low voice.
"Finding the median of two positively ordered arrays."
"Given two positive-order (from small to large) arrays nums1 and nums2 of size m and n respectively. Please find and return the median of these two positive-order arrays. The time complexity of the algorithm should be O( log (m+n)).”
When hearing the question requirement, Shen Ruhai's pupils shrank instantly.
At first glance, this question is just about finding the median, not even easy.
But to meet the latter time complexity, it is not a simple difficulty.
After thinking about it, he asked Qi Yumo softly: "What's the question number?"
"It seems to be 1178."
Shen Ruhai glanced at Ye Ming, then opened the website and found the same question.
Then, he began to analyze the meaning of the question.
"Well... this question is to find the median of two ordered arrays, and the time complexity is limited to O(log (m+n)), so the time complexity should be based on the dichotomy method."
Shen Ruhai thought quickly in his mind: "This question is not difficult. The difficulty lies in the time complexity. You need to define a function to find the specified element in two ordered arrays..."
Time passed by second by second, and while he was still analyzing, Ye Ming opposite him was already typing on the keyboard silently.
Qi Yumo's eyes also became surprised.
After a while, Ye Ming's voice suddenly woke up Shen Ruhai.
"The first question is ready."
Shen Ruhai was slightly startled. When he realized that Ye Ming said he was done, he stood up and strode to Ye Ming's side.
Then, he saw Ye Ming press the submit code.
successfully passed.
The execution efficiency and memory usage both exceed 80% of the code.
"I'll move on to the next question."
Ignoring Shen Ruhai, Ye Ming pressed another question.
This time, it is a question of medium difficulty.
He completed the submission in just three minutes.
Just when he was about to click on another question for the third time, Shen Ruhai suddenly exhaled slowly.
"No need, you can study Luogu or ACM real questions."
Ye Ming looked up and saw that the blush on Shen Ruhai's face was slowly dissipating, and there was an inexplicable meaning in his eyes. This means that there is sadness and relief.
"Then...can I stop reading for a while?" Ye Ming closed his notebook and spread his hands: "I've been a little busy recently."
"Are you busy with the RC National Competition?"
"no."
"That is?"
"...Well, it's just a project, but don't worry, I won't hold you back." Ye Ming looked at the two of them with a smile.
Shen Ruhai, Qi and Mo looked at each other, with wry smiles appearing in their eyes at the same time.
