The school beauty said she lost her memory

Chapter 157 I’ll rub it for you when I get home
"The B-tree insertion operation algorithm and deletion operation algorithm in "Data Structure (C Language Edition)" both involve the concepts of post-split and post-merge. Among them: Insertion operation algorithm: post-split. Delete operation algorithm: post-merge ."

"This is different from the algorithm for basic B-tree operations in "Introduction to Algorithms". If you use the algorithm for basic B-tree operations in "Introduction to Algorithms", the answer you get will be wrong."

"The teacher said before that "Data Structure (C Language Version)" shall prevail."

When Liu Shuyao came back, she happened to see her boyfriend drawing something on paper with a focused expression.

There were two girls sitting next to me.

"The pre-split of the insertion operation may require splitting the root node. At this time, a new root node needs to be created, and the height of the tree is increased by one. So this option is correct."

"If the deleted keyword is located in a leaf node: delete the keyword in the leaf node"

"If the deleted keyword is located at a non-leaf node."

Xiang Ran did not speak slowly when explaining or deducing the process. After explaining for a few minutes,

Direct and clear: "So choose C!"

After finishing speaking, he first glanced at Liu Shuyao, then turned to look at his classmate:
"Did I understand?"

Liu Shuyao didn't understand, so she sat across from him.

But she felt that the two girls seemed to understand somewhat, but they still nodded.

Especially after seeing her coming, he seemed even more excited.

Isn't that the problem?

How does it feel weird?

"Got it! Got it!"

"Thank you!"

"You guys go on a date~ We won't interrupt you!"

Then he left in a hurry.

Liu Shuyao felt embarrassed and put the cup in front of her boyfriend's table, muttering.

"We're obviously not dating~"

"How about going on a date now?"

Xiang Ran held his girlfriend's hand and leaned closer to ask her.

Obviously Liu Shuyao was more interested in this. Her eyelashes flickered and she clasped Xiang Ran's palm.

"Have you finished your review?"

"Let's talk about it tonight. I'm so dizzy right now that I can't see anything!"

Since my boyfriend said so,

"Then where should we go on a date?"

Then Xiang Ran leaned into his girlfriend's ear and said something unknown. All he saw was Liu Shuyao's cheeks turned red. She lowered her eyes and pushed Xiang Ran.
It seemed that he had heard something terrible.

The two people quickly packed up their things and left the library.

The two girls behind me were filled with excitement.

"Wow~"

"Are top students even so flirtatious when they fall in love?"

"We are all NPCs, right?"

"What did you say he said to the school belle? I blushed when I saw Liu Shuyao!"

"Did you remember the problem-solving process that Ranshen mentioned just now?"

"what?"

"No!"

"Sister! Then I think your data structure may not be able to pass!"

"."

When Liu Shuyao stood in the badminton hall with a badminton racket,
The expression on his face is not very pretty.

"Is this the kind of sport you call a sport that can make people feel adrenaline soaring, blushing, and their hearts beating?"

Because it was the end of the semester, there were not many people in the gym, and there were just four boys playing. The "bang bang" sound of badminton rackets echoed in the gym.

But it seemed that because it was dinner time, they left without playing a few balls.

Light blue badminton hall signs are hung around the court, and bright lights cast mottled shadows on the walls.

The place suddenly became quiet.

Xiang Ran shook his racket, planning to warm up first:
"Isn't it reasonable?"

"Didn't you say you haven't been sleeping well recently? Are you a bit insomniac?"

Liu Shuyao also swung the racket, but it just hit her boyfriend on the butt.

"Humph!"

"What a theory!"

Xiang Ran saw his girlfriend staring at him fiercely with a pair of watery almond eyes, her little face bulging with anger, and her claws stretched out towards him fiercely.

And he complained pitifully word by word:
“I can’t sleep because I’m not with you!!!”

"."

It's over,

This was a failed attempt
Xiang Ran looked at Liu Shuyao angrily and didn't know how to explain the relationship between exercise health and sleep.

"Badminton is an aerobic exercise that helps release tension and stress, making it easier for the body and brain to enter a deep sleep state."

"Moreover, it's a whole-body exercise that can be consumed."

Xiang Ran looked at his girlfriend and his face became even worse!
"Then go back and stay tonight?"

He spoke tentatively. The two of them seemed to have not gone back to live together for a while.

After achieving his goal, Liu Shuyao held the badminton racket in his arms and nodded aggrievedly.

"Let's go now?"

"What about this?" Liu Shuyao looked at the venue where her boyfriend had made an appointment.

"Forget it~"

"Then, let's finish the fight!"

So, the two of them played badminton for another hour.

After all, we brought some competitive sports,

Liu Shuyao tied her hair into a high ponytail.

Start warming up.

The thick coat in winter was a bit in the way, so Xiang Ran put away his and Liu Shuyao's clothes in the cabinet.

When he turned around and came back, Liu Shuyao had already started stretching. He stretched his hands to a high place and raised his body slightly, feeling the stretch of his back muscles.

The fingers are crossed flexibly, clearly showing the soft body.

Xiang Ran didn't expect that the bottoming shirt his girlfriend wore today was a little tighter and slightly tight, highlighting her slender waist and slender waist.

Especially when stretching sideways, the curves are simply displayed to the maximum extent.

The lines of the side waist and hips form a beautiful sexy arc under the light.

"Clap" sound,
Xiang Ran slapped Liu Shuyao's bent butt right in the face.
"Let's start~"

"I'm not done yet!"

Liu Shuyao muttered.

Xiang Ran tilted his head.

After calming down, at least I remembered that I came here to exercise!
The warm-up is over,

Xiang Ran served the ball smoothly and powerfully, waving the badminton racket and accurately crossing the net with a "shoo". Liu Shuyao stared at the flying ball and responded accurately.

Or cleverly adjust the angle to change directions in the air.

Over and over again,
The court was filled with the sound of swinging wind and the slight sound of the ball hitting the racket surface, creating a tense atmosphere.

But gradually Liu Shuyao, who has a basically inactive physique, started to feel tired.

My swing is no longer so resolute and powerful, especially after losing two balls, I feel a little sore in my arm.

"Pause Pause!"

"Let's take a rest~"

Then he walked to the bench and sat down.

Xiang Ran walked over and saw Liu Shuyao breathing rapidly, panting slightly. A little sweat lightly moistened the raised collarbone, making it look particularly shiny.

Because of the exercise, her cheeks flushed a bright red, and the blush outlined her entire delicate feeling, as if the air around her was tainted with some pink flavor.

He also spoke in a feeble and apologetic manner, slurring his words.
"Honey, I really can't do it anymore~" Liu Shuyao raised her arm slightly and rested her little head on Xiang Ran's side, as if she had found support.

"It hurts here!"

Then he took Xiang Ran's hand and pointed to somewhere on his body, with some aggrieved sorrow in his tone.

Then, he pointed to his calf,
"This part hurts too~"

"And my waist, oh, I feel like I can't feel my waist anymore!"

"Why are you so tired from playing badminton?"

Xiang Ran felt that his girlfriend's coquettish voice became more and more obvious. He lowered his eyes and revealed a gentle tone in his words.

"I'll give you a massage when I get home?"

"Hmm~"

"Then let's go!"

If Liu Shuyao was a little pretentious at first, but after taking a shower, her hands and arms really felt sore.

So I put on my slippers and ran to the second bedroom to complain to my boyfriend.

Xiang Ran was still flipping through the review materials.

Just when Wang Hao called, the two of them were talking about today's question.

When he saw his girlfriend coming out, he pointed at his cell phone.

Liu Shuyao nodded. She only wore a very short suspender skirt, which could only cover her legs.

I glanced at the disgusting plastic stool, thought for a moment, and just sat on the table without looking at it.

Xiang Ran was still on the phone,

"I also encountered this question when I met Yu Wenwen in the library today."

"If the number of keywords n ≥ [m/2]-1 after deleting the node, there will be no subsequent operations."

"If the node deletes the keyword and the number of keywords is n<[m/2]-1, then it needs to borrow a keyword from the sibling node. This is divided into two situations: the sibling is enough to borrow and the sibling is not enough to borrow."

"So whether it is located at a leaf node or a non-leaf node, the leaf node must change at this time. Then this is correct."

"But III. All nodes in the B-tree can store keywords. If the searched keyword is located in a non-leaf node, it is impossible to find the leaf node."

"This has to be wrong."

"So choose C."

Wang Hao: "What about the 9th path?"

Xiang Ran glanced at the information in his hand and found that the information with question 9 was probably pressed under Liu Shuyao's buttocks.

So he looked at his girlfriend's short skirt and pointed at his information.

Liu Shuyao then realized something and handed the thing out with a blushing face.

Ahhhhh!

She thought it was unnecessary!

Xiang Ran took it without thinking too much,

But why does the usually cold page bring some warmth?
The pages of the book have also been compressed and flattened a lot!
He gave me a slap in the face,
"that."

Wang Hao: "Have you found question 9?"

Listening to the voice on the other end of the phone, Xiang Ran concentrated again before finding the ninth question in order.

"Weighted average length of Huffman coding?"

"Did you choose C?"

Wang Hao: "Yes."

The tip of the Xiangran pen is drawn across the surface of the document. It is obvious that the paper is smooth, but even writing does not feel smooth.

I read that question several times, but I can't seem to form a decent sentence.

After a long pause,
“加权平均长度为(3x3+3x4+3x5+3x6+2x8+2x10)/(3+4+5+6+8+10)=2.5，如果不考虑权重，会错误计算为(3+3+3+3+2+2)/6约等于2.67。”

"Because the frequency of occurrence of each character is 3, 4, 5, 6, 8, 10, respectively, and the weight."

"It's just frequency!"

"should."

"It should be choice B."

The two people didn't talk on the phone for long. In the end, Xiang Ran had no intention of following Wang Hao. He only said that he would read the information again tomorrow and hung up the phone in a hurry.

hang up the phone,

He frowned, looked at his girlfriend's skirt that was a little shorter, reached out and pulled it down.
It didn’t help at all, so he asked:
"Is not It Cold?"

Liu Shuyao shook her head, hugged her boyfriend's neck from the front, and pressed her soft touch against Xiang Ran's chest.

He reached out and pulled the person in front of him, wondering what was going on with the dress.

Then I heard Liu Shuyao ask:
"Have you finished the book?"

"Uh-huh."

"Then I want to eat strawberries~"

So Xiang Ran got up and went to the kitchen, "I'm going to wash now."

After all, it was winter. Xiang Ran first took a basin of warm water and put the strawberries in one by one.

As I was washing, my thoughts were all about my girlfriend’s skirt that was half too short.
Xiang Ran felt a slight anxiety in his body, as if a hot atmosphere was filling his surroundings.

calm!calm!
What is rear splitting?

never mind! ! !

In order to calm my inner uneasiness,
He reached out and adjusted the temperature of the faucet, turning the warm water into cold water.

The cool water drops fell on Xiang Ran's hand, cooling him down instantly.

Xiang Ran frowned slightly, feeling the refreshing touch of the cold water, as if ice and fire merged at that moment, gradually cooling down the heat in his heart.

The cool water slid over his fingertips. The strawberries were floating in the cool water, and water droplets rolled down from the fruits.

The washed strawberries were placed in a glass bowl next to them, shining with an attractive color through the clear water drops.

Xiang Ran shook off the water stains on his hands and waited for him to come back.
I found that my girlfriend hadn't left yet, her slender calves were swaying, and her white and tender feet seemed to be stepping on clouds.

The hair is spread softly on the side of the body,
The delicate eyebrows outline beautiful outlines under the desk lamp.

Seeing Xiang Ran coming over, she immediately stretched out her hand, brushed her nose against his neck, and smiled sweetly.

"I can't find my slippers, I have to carry them over~"

Xiang Ran glanced at the slippers hidden under the seat.

Didn't say anything,
But as soon as he touched Liu Shuyao’s waist,
The excited person said "Ah",
"Hmm~"

"Why is it so cold?"

Liu Shuyao didn't seem to expect that her boyfriend actually washed the strawberries with cold water. She took Xiang Ran's hand and put it in her arms to cover it again for a long time.

The soft touch comes up with the temperature,

Xiang Ran felt that his strawberry was wasted.
He held his legs with one hand and his waist with the other, and carried her to the master bedroom.

"I'll go put away the books and get the strawberries."

Liu Shuyao nodded, picked up Eleven who was sleeping soundly on the bed, and took two deep breaths.

Xiang Ran quickly put away his schoolbag. After entering the room, he saw his girlfriend curled up comfortably on the soft bed. The white sheets were like a fluffy cloud, gently wrapping her body.

The room was filled with a light aroma, the sweet taste of strawberries wafting in the air.

"Is the one you bought today sweet?"

Liu Shuyao picked a big one and stuffed it into her mouth. The surface of the strawberry was covered with tiny fruit particles, as if the delicate particles were adhered to the pulp, forming the unique rough texture of the strawberry.

The sweet and sour juice exploded in her mouth, filled with a strong fruity aroma.

"Hmm~"

"A little sour."

Liu Shuyao narrowed her eyes, and then fed one to Xiang Ran.

"It's really not as sweet as the one I bought last time."

Xiang Ran sat on the bed, occupying more than half of Eleven's seat. The little cat's head was lowered, hesitating in which direction to move.

Finally, he reluctantly lay down at the foot of the bed.

Then he turned his head angrily and fiddled with the sheets with his small paws, trying to leave some traces of himself on the place occupied by Xiang Ran.

The big tail swings in the air and sweeps it around hard, leaving more of its own flavor.

Xiang Ran patted his leg,
Facing Liu Shuyao,
"Come here~"
