The way for sophomore major students to retired

Retiring from military service and returning to school
Now that I have retired from military service as I wish to return to school, it is almost like a dream to walk on campus after opening the journal. It is so happy. When I think that I still have three years of university life, I will cherish it. Because of my two years in the military, I realized that going to school is really a happy thing. How many nights I stand at night, I think about the life on the university campus. At the time, it seemed that it was two years later to go back to school. At that time, it seemed that my university ceased to exist in this world. Because the university and the army feel completely two worlds. Today is 9.13. Although the transfer procedures and some other procedures have not been completed yet, classes will officially start tomorrow! I am so happy and so excited!
I went back to school at 9.7, completed all the formalities I could do in one day, and started learning at 9.8.
I remember that in June, the army said that it would be 3 months to finish the C language and data structure, and finish the OJ of Zheng Qinggong. But because of the special circumstances of the unit at that time, it was unable to continue, even after the lights were turned off, there was no time and mood to study.
From 9.8 to 9.11, I took my notebook for self-study every morning and afternoon. I still looked at Hao Bin’s C language and started directly from the pointer to see the structure. It is necessary to lay a solid foundation of the C language for the freshman year in order to deal with the beginning of the class "Data Structure".
On 9.11, I brushed the 2h questions, AC 7 channels,
9.12, I spent almost a day in a survey report of the whole college, did not study, but also learned things like official document writing
9.13 I was interrupted in the middle of this morning, and I read it. A question is a question that took 1h to find various bugs and make various changes the day before yesterday. Today, the amount of code in the book I read is only one-third of what I wrote myself, so I spent time carefully pondering the way the code in the book is written. At the beginning, I didn’t study it thoroughly, but later I summarized every variable in the for loop on a piece of paper before I understood it. It turned out to be a sequence of numbers and the most basic and basic mathematics. That is, when constructing the judgment conditions of the variables in the for loop, the formula is difficult to find, but if you list the value ranges of each variable, you can barely get it together, but it takes a little time. In the future, it is best to remember this type of question and this type of formula.
