Goal: Master C language proficiently for three months, learn data structure and algorithm
Today is the first day to decide to brush OJ.
Brushed 13 channels in an hour.
At the beginning, the previous ones are quite simple. Today, I mainly understand the problem of float and double input and output format symbols.
The next day, I scanned 16 channels in an hour, and I still felt very simple. I reached the 31st question, and I felt that there were not many algorithms involved. The difficulty is not as good as the difficulty in the algorithm book, so let's go ahead. Will listen to the data structure later.
-The third day. No OJ questions today. Only one question about fractional decimals was done. I thought about it for half an hour, looked at other people’s code research algorithms for half an hour, typed in to find bugs and looked for an hour (just because the scanf lost an extra %, and the compilation did not report an error)
On the fifth day, I was still studying the problem of fractional decimals yesterday. Doing the math, I have spent five and a half hours on this, of which the real algorithm is only half an hour, and the rest is spent designing code, writing and understanding the flow of the program to run in my head, and finding bugs , The last bug is due to a lack of understanding of program flow control. How can you improve yourself quickly in less than three months after leaving school? If you only do algorithmic problems, you still do it by yourself. It may take a few days to do one problem, and it will only take dozens of problems in three months. So I decided that for me who want to change my major, it’s still far from the time to write a question, because I am proficient in a language, and then I can look at the data structure and algorithm on station b, and I just need to engage in this subject. With learning, the effect is much better than just holding one's head. Continue to experience more than a dozen episodes of the c language of teacher Hao Bin at station b.
The sixth day. I feel very tired today. I have been working overtime after get off work in the afternoon. I have to work until 12 o’clock in the evening. I’d better take a moment to write a blog as a vent. The school will start in three months, and it’s pretty good. Now that I think about it, campus life in the university is really wonderful! If you have enough time for yourself, no one is bothering you, so you must cherish your campus time. Tomorrow and the day after tomorrow, I hope that there is nothing wrong. You can watch the video carefully. In two days, you should be able to breathe for 18 hours and half of it. It is estimated that you can finish watching c next weekend. Then, just look at Hao Bin's data structure and do the algorithm by the way, hoping that the school will not fall too much.
On the eighth day these days, I used the time after get off work in the evening to learn until 12 o'clock every night, watch the video until 10 o'clock, and do my own practice until 12 o'clock. Now I have 120 episodes of Hao Bin's C language introduction. Even on Sunday, there may not be enough time to study. Work overtime until nine o'clock in the morning, and also in the afternoon. The 40-minute video has been seen one after another. Now, this is just coming back, it's half past seven. Now that I think about the life in school is really wonderful, this experience also made me learn to cherish time more. There are still three years of university time when I go back. There is much more time than here, but there are too many things to learn. Come on!
ninth day. It was still a night interrupted intermittently. It's Episode 139, come on! Hope to finish this week.
On the fourteenth day of 6.14, I don't want to watch more than 170 episodes. I have always been unable to study quietly recently.
9.9 Today is 9.9, and it's the third day since I retired and returned to school. After two days of self-study, I still reviewed Hao Bin's C language. I started directly from the pointer. From 120 episodes, I saw 160 episodes. Sure enough, I had plenty of time. These three months failed to achieve the learning goals due to objective factors, but it was fine, and now it has just begun!
