I interview Suzhou Taiwan's experience Lenovo now ◎ Flower copyright, refusal to reprint some of the cases of RPESXB2WDX learning programming, I really feel deeply, this interview makes me deeply experience the failure but also harvested a lot . I have to say it into three parts, 1. Yes ◎ Flower copyright, refuse to reprint ◎ Qnvrntehvn I interviewed the specific passage 2. 3. I think about it. Today I should do it.
Of course, these words are largely my personal opinions, it is impossible to get everyone an agreement, so ◎ Flower copyright, refuse to reprint ◎ VN94TJRW40 in some views If a friend feels with me, please Don't mind, don't attack me, just when I have not said, welcome to contact me to discuss these issues!

He said that there is no mistake, and the difference between the three procedures run is simply the difference between the three programs when N is very large. When I just wanted to speak something, he first opened: "Don't think that the CPU calculation speed will push all the questions to it, the programmer should optimize the code and optimize the code.

At 5:30, the interviewer asked me to wait for us, so I left their company.
This is the whole of the interview! ◎ Flower copyright, refuse to reprint ◎ zhuhwwnqye ◎ Meteor copyright I remember the big rain in that day, the temperature is very low, I think, I have been walking from 5:30 to 7:30, the whole body is wet, and I am cold and hungry, but I am just walking, my mind is full Doubt, I also want the rain to wake yourself! Seeing some friends here may think that if you don't make yourself, I will definitely believe in you, because I have never doubted Chinese programmers, I think China has the best procedures in China. Member, I have never thought that I have a master, so I can't do it. I don't mean that the Chinese programmer is poor than Taiwan or other places, so I am from my angle, I want to talk about some feelings: ◎ Flower copyright, refuse to reprint ◎ WR988QMIVJ ◎ Meteor copyright What is the proportion? Taiwan, I don't know, have a few of China's 100 programmers? I can't count, from the above performance is enough to explain everything! Is it 1? 5? 10? 50? I didn't dare to mess with this number, I was hurt by netizens, then how many people in our country learn computer? Take our school, 4 classes of the computer 97, 5 classes, 98 classes, 10 classes, 17 classes in 2000, more people, what should I do? Our school's practice is to let the graduate students, and then? After a big settlement, a lot of money fell into the pocket of the school, but also said that the current student is low! It's really funny, I don't know what the school is doing for what is to cultivate a lot of programmers in China? Can students really learn computer knowledge? Ok, I dare, in our school to learn programming students and outstanding programmers (note that I refer to excellent, only a few bad programs, people can't calculate) should be 100: 0.1 ◎ Meteor copyright Refuse to reprint ◎ Yaoddjqhct In this proportion, although our Chinese learning programming people are covered, think about how many individuals can truly contribute to the development of China's software industry, and how many people can truly write outstanding programs! ◎ Flower copyright, refuse to reprint ◎ PDMKXWFZEI ◎ Flower copyright We have real emphasis on the efficiency of the program and the quality of the program? We have a careful analysis of what we write, see if there is any way to improve, see if there is a simple way to achieve the same purpose? I asked, I found out that I have never optimized the procedure I wrote, up to DEBUG, but this is enough? These days I occasionally discovered a game I have written. It was when I first added www.vcroad.net as one member a year ago, I feel that I should take something out, then spend a week's time written. !
The procedure is not complicated, but it has been used in a lot of data structures, and has used a wonderful algorithm, plus Windows interface and game playability. After writing a lot, I was really admired. Yourself! But now: No comment, a lot of ugly functions such as: void chushihua (), there is no necessary variable, you can use the simple statement to complete the work I use the gorgeous algorithm, a large number of global variables ....., If you say that you can listen, the more than 600 rows of procedures are a gap in addition to running! If I can hear some backspinses a year ago, I probably I can realize it, but since I heard since the original code, I heard the words of praise, no one filed me to improve the proceedings of procedures, this is What is the problem? Very worth thinking! ◎ Flower copyright, refuse to reprint ◎ 7ophhhqops ◎ Flower copyright, refuse to reprint ◎ SDRDSP7JZV has a doubt is: Does we say and do really? When I was in the school, I was assigned to a computer contest. I invited a teacher to go to the finals, mainly some algorithm topics, this teacher may be the only teacher in my university, from the program debugging to score, For each program, the time efficiency and space efficiency is taken carefully, then comprehensive score, forty people's rolls, and the teacher debugged from three o'clock in the evening, and after some written wonderful statements, I added annotation. I am so happy to have such a teacher and do an in-depth communication with him, but after the matter, I have a unpleasant thing, and I got the second student in the game to find me, saying that all the procedures were successfully debugged. He is full, and it should be first, I said he, finally tested his original procedure and the first original procedure comparison, good, both programs are running very well, then the classmate said: "My program is written very simple, only the number of questions completed the requirements, but he wrote a lot, why gave him more points.
"I was very angry. If it is not the teacher's responsibility, then the first place and the second place really want to intermodize, please, the less the number of procedures, the higher the quality of the program, I remember me He talked about this truth, and finally persuaded him! Haha, but I can only talk, I don't know how many people have, saying that my head is the way, but I have never valued it! ◎ Meteor Copyright, refuse to reprint ◎ LydtqyTfb1 ◎ Meteor copyright, refuse to reprint ◎ ll1mlnwcif3. I plan to do it! ◎ Meteor copyright Guess the netizens of this article probably have a belly, a belly complaint, borrow this article venting, not what I want to achieve, I don't have a worthy of my own one, but in some I really do something wrong, or it is deviated from the right direction. Now it is when it is correct and reorganizing the kuman. I believe in the best programmers in the world, I also believe in me. The level will not always keep the status, I will clean up the truth now! ◎ Flower copyright, refuse to reprint ◎ Ativrksqmf is really skillful, I will read this manual online when I write this manual online, I I don't know what to indicate, but I think if I have been doing this basic principle, I will implement my ideal - an excellent software designer! ◎ Flower copyright, refuse to reprint ◎ z1pedzknyw ◎ Flower copyright, refuse to reprint ◎ Opiptyhmlq (below these words is not my original, I am thinking about it online, I am really fortunate to see these, this article also ends with the following text, I sincere I hope that you can get inspirated from this article.

Because it is more than the real master, it is too far away. There is no shortcut in the world, but some basic principles It is possible to follow. ◎ Flower copyright, refuse to reprint ◎ JTH0LN47AI ◎ Meteor copyright , It is difficult to write high levels of programs. According to my observation, people who learn computer majors can more written high quality software than others. The program will write, but when you find that it is difficult to write a certain degree, it should think about whether it is to go back to learn these most basic theories. Don't go to learn OOP at the beginning, even if you are fine, you may have no hand when you encounter some basic algorithms. ◎ Flower copyright, refuse to reprint ◎ 6LKIWZCI0W ◎ Flower copyright, refuse to reprint ◎ JVHQG2WSZY 2. Rich imagination. Don't stick to a fixed thinking method. When you encounter problems, you should think about several solutions to solve the problem, try the way others have never thought about.
