The programmer and his woman

The next morning, I walked into the school gate and felt that the atmosphere was a little unusual. When Sun Lingling saw me, she immediately smiled brightly. She changed her mocking attitude from yesterday and became like a little fan girl. She walked over quickly with sparkling eyes, as if she had found some treasure in me.

"Teacher Wang, you look so handsome today, you are simply a male god! How can you become so handsome just by changing your hairstyle?" She exclaimed exaggeratedly, making me touch my hair embarrassedly.

"I'm going to get some water," I replied, preparing to turn around and leave.

"Just sit there and don't move. I'll help you fight." Sun Lingling hurriedly stopped me, looking eager to try.

I looked at her helplessly, "Sun Lingling, don't you feel embarrassed when you keep looking at me like this?"

"I don't think so," she answered without hesitation, as if my question was strange.

"But I think." I sighed, trying to make her understand my troubles.

"Just pretend I don't exist." She waved her hand nonchalantly, and then asked me curiously, "Hey, Teacher Wang, where are you going again?"

"I'm going to the bathroom." I answered truthfully.

"Oh, you can't follow me to the toilet." She seemed a little disappointed, but then she thought of something, "Oh, by the way, did you bring toilet paper? I have some here."

"I was peeing." I explained with a helpless smile.

"Oh, yes, you don't need paper to urinate." She suddenly realized and started looking for the next topic.

Just then, I met Mr. Li Lei, who was about to go to class. I immediately called him, "Hey, Mr. Li Lei, do you have a class now?"

"Yes, I have classes. I'm going to class now." Teacher Li Lei replied.

"I'll hide in your class for a while." I suddenly expressed my desire to attend his class, and Teacher Li Lei was obviously a little surprised.

"Who are you hiding from?" Teacher Li Lei asked curiously.

"Sun Lingling, she might have taken the wrong medicine today." I shrugged helplessly, "But I do want to learn 3D modeling from you. Remember to call me when you have classes in the future. If I have time, I will go to your class and listen to it."

"Okay, come on." Teacher Li Lei agreed readily, "I'm not interested in programming, why don't I also go to your class for free?"

After class, I returned to the office and saw Teacher Qi looking for me. "Hey, apprentice, where have you been? I've been looking for you for a long time."

"Oh, I just went to listen to Teacher Li Lei's class and learn from him." I replied with a satisfied smile on my face.

"Well, that's good. Young people love to learn." Teacher Qi encouraged.

I took a few steps forward and asked, "Master, do you want to talk to me about something?"

The master nodded and said quickly, "Well, our advertisement needs to be re-formatted. I have prepared all the relevant materials. Send them to your classmate at the newspaper and ask him to update our advertisement as soon as possible. It will be published today."

"Oh, OK." I responded, and then prepared to copy the material, "Where is the material? I'll copy it right away."

"Here, the materials are already on my computer." The master said, pointing to his computer screen.

I walked over, opened the folder, and prepared to copy the materials. However, when I saw the advertisement picture, I was stunned. I exclaimed, "Oh, Master, this is a crackdown period, can you send this picture out?"

The master seemed a little embarrassed. He scratched his head and said, "I don't know either. I just asked a student for this. I told him I wanted an eye-catching game picture, preferably a female character with big breasts and big buttocks, which can attract customers at first sight. As a result, the student gave me this picture and said it was a promotional poster for the game. I think this picture is indeed eye-catching, but I don't know if the newspaper will approve it."

I shook my head helplessly and said, "Master, it's not as simple as just catching your eyes when posting this picture. If it goes wrong, you might get caught as well. So don't worry about it. I'll find a picture that meets your requirements and can be posted later."

After hearing this, the master seemed relieved. He patted me on the shoulder and said, "Hey, I've been waiting for you to say this. I will no longer be in charge of this matter. I'll leave it to you. By the way, I have some private work to do, so I'll go take care of it first." After saying that, the master left the office in a hurry.

Looking at the master's back, I couldn't help but smile bitterly. This master really made me laugh and cry.

As I walked into the classroom, a clear whistle broke the silence, followed by the sound of students talking in a flurry.

"Teacher Wang has changed his look again. He looks so handsome today!" A naughty boy shouted, "Teacher Wang, I want to give birth to a baby for you." This made the students around him laugh.

"Go, do you have that ability?" I replied jokingly, causing the whole class to laugh again. Then, I clapped my hands and said seriously, "Okay, no more joking, let's start the class. Today we are going to talk about judgment and choice."

I started today's class and the students gradually got into the learning state. However, I noticed that one student seemed a little absent-minded, so I paid special attention to his reaction.

As soon as I finished explaining a knowledge point in this class, the student came to me.

"Teacher, I've heard what you talked about today when I was in college," he said a little embarrassedly.

I nodded to show my understanding. Then I asked, "Oh? Do you have any questions for me?"

He hesitated for a moment, then asked, "Teacher, which one do you think will take less time to execute, judgment or selection?"

I pondered the question raised by the student, and I felt that this was a question worth exploring in depth. Although in daily programming, we often choose judgment or selection statements without thinking, but if we look closely, their execution efficiency is indeed different. The use of selection statements is indeed relatively fixed and the writing is relatively cumbersome, while judgment statements are more flexible. However, my personal programming experience tells me that the execution speed of selection statements seems to be faster.

As for the specific time difference, I really didn't know. I decided to go to the office to look up relevant information to give a more accurate answer. Just as I was about to leave the classroom, I ran into Teacher Qi. I thought to myself, this is a good opportunity to ask for advice.

"Master, I have a question for you." I said respectfully, "A student in the class asked me which statement takes less time to execute, a judgment statement or a selection statement, and the specific time difference."

Teacher Qi smiled and praised, "Oh, it seems that this student is very good at thinking. If you have such a student in your class, you should focus on training him. How about this, you go and call that student together, and I will show you."

Teacher Qi opened a program and began to explain: "This is assembly language. There was no concept of function in early computer codes. Jump statements were used to execute code. Look at this jump statement. Doesn't it look very similar to a select statement in structure? In fact, a select statement is a jump when it is executed. It is also the code form that is closest to the early days when computers had insufficient computing power, so it executes faster. Now let's compare the execution time of these two statements."

Teacher Qi operated the program and printed out the execution time of the two statements. We can clearly see that the selection statement is at least three times faster than the judgment statement.

Teacher Qi continued with emotion: "Compared with our time, the speed of computers has changed dramatically. If you programmers today can still write code with the idea of ​​saving memory and CPU as our older generation programmers did, it will be quite a remarkable thing. Look at the games and programs nowadays, which are hundreds of megabytes or even thousands of megabytes. Think about how we used to complete a program with similar functions with just tens or hundreds of bytes. It was not easy at all."

This remark touched me deeply. I thought about the current situation of mobile phone applications. The processing power and storage capacity are relatively limited. Optimizing the code structure and image size has become the key. I realized that in the future, even if mobile phone applications become larger and larger, we still need to pay attention to the execution efficiency of the code, even if it is only to improve it by a few tenths of a second.

Finally, Teacher Qi instructed me: "Teacher Wang, please sort out our research results today, print them out and post them in the learning column in the corridor for students to study and refer to." I gladly agreed, my heart filled with love and awe for programming and teaching.

After countless attempts to dial that number, I was almost in a desperate expectation. Finally, this time the call was connected. I held the phone tightly, my heart was beating so fast that it almost burst out of my chest, my ear was close to the receiver, and I asked in a trembling voice:

"Hello, is this Ji Ruoxi?"

A faint but familiar voice came from the other end of the phone: "Yeah."

I immediately said excitedly: "Ruoxi, I'm your elementary school classmate Wang Dong. Long time no see! How have you been recently? Is everything okay?"

There was silence on the other end of the phone for a while, and she seemed a little overwhelmed. I was a little worried, wondering if she had forgotten about me, her long-lost classmate. The atmosphere was a little awkward, and I could only try to break the silence with a relaxed tone.

I continued, "Ruoxi, you didn't come to the last class reunion. We all missed you."

She sighed softly and replied, "I'm no longer in the same city as before, so I can't participate."

I asked with concern: "Where did you go?"

She hesitated for a moment and said, "I'm in City A now."

I was a little surprised and asked, "Have you moved?"

She shook her head and said, "No, I'm just working in City A."

I was even more puzzled and asked, "City A is a big city. Why did you go there to work as an operator? How are you doing there? Why don't you come back? Our school is still short of people. I can talk to the leaders of the unit and ask you to come work here. This way you will be close to home and your family can take care of you."

She was silent for a moment, then said softly: "Thank you, Wang Dong. But I really don't want to go back, and I can't go back."

I was a little confused by her words, so I asked, "Why do you say that, Ruoxi? I ​​feel like something is wrong with you. Where are you in City A? I want to meet you and talk."

She seemed to hesitate for a moment, then said, "I went to Shuangqiao Road last time on a business trip. Is it close to where you are?"

When I heard this, my heart tightened because that place was not far from the hotel where I stayed when I was on a business trip. Just as I was about to answer her, suddenly there was a cry of surprise from the other end of the phone: "Ah!" followed by a long silence.

I asked anxiously, "Ruoxi, are you okay? Are you still listening?"

However, the only answer I got was the "beep, beep" sound from the other end of the line. I was panicking, not knowing what had happened. I called her again, but no one answered.

I thought it was because of a bad signal that caused our call to be suddenly interrupted, so I tried to call Ji Ruoxi again. However, this time, a cold mechanical voice came from the other end of the phone: "Hello! The number you dialed is powered off. Sorry! The subscriber you dialed is power off."

I was stunned. What was going on? Was her phone out of battery? However, thinking back to our brief conversation, especially her surprised cry when she heard the name Shuangqiao Road, the silence that followed, and the sudden shutdown of her phone, all seemed so unusual that I couldn't simply attribute it to the phone being out of battery.

Just when I was full of doubts, a strange yet familiar voice suddenly echoed in my mind: "I'm cheap, can you come and play with me?" This voice was somewhat similar to Ji Ruoxi's voice, but not exactly the same. I was shocked. Could it be her? But then I shook my head. How could this be possible? It was absolutely impossible. Ji Ruoxi has always been an upright and kind girl. She couldn't say such a thing. I must be imagining things.

After the morning class, I tried to call Ji Ruoxi again, but it was still turned off. I started to get anxious and couldn't wait any longer. What if Ji Ruoxi really got into trouble? Even if the girl who looked like her had nothing to do with her, I couldn't just sit there and do nothing. I decided to go there in person to see if I could find her.

I had no classes in the afternoon, so I left school early. This time I learned from my last lesson and brought enough money to deal with various situations that might arise. I took a bus to the street where I saw the girl last time. Maybe it was still early, there were not many pedestrians on the street, and I didn't see the type of girl I met that day.

I wandered on this street for a long time until night fell and the lights on the street began to light up. But I still didn't see the girl, nor did I meet the girl I saw that day. Just when I was about to give up, a taxi driver who was waiting for work stopped me. He was tall, wearing casual clothes, leaning against the door, and shouted to me in a nonchalant tone: "Dude, you've been hanging around here for a long time, what's the matter, looking for a girl?"

When I saw him calling me, I thought that taxi drivers are usually well-informed, so I could ask him for information. So I trotted over and said to the driver breathlessly, "Hello, sir. I want to ask you if there are many women on this street at night?"

The driver glanced at me with a playful smile on his face. “Hey, I guessed it right. You’re just looking for fun. Don’t wait. This place is gone.”

"Gone? What does that mean?" I asked anxiously.

"There was a concentrated cleanup of this area last month, and a lot of people were arrested. Now they don't dare to come here." The driver answered nonchalantly.

I sighed in disappointment, but asked unwillingly: "Then driver, do you know where they went?"

The driver looked at me and then laughed: "Why are you so anxious? Come on in the car. I really know the place."

I hesitated for a moment, but thinking that Ji Ruoxi might also be involved, or at least have some connection with these places, I decided to go and have a look. So I got in a taxi and followed the driver's instructions to a new place.

The driver stopped the car, pointed to a row of buildings ahead and said, "We're here. This is it."

When I got off the car, I saw a row of simple bungalows with a "Hairdressing Shop" sign hanging on the door and ambiguous lights coming from inside.
