I don't know why I want to write this text, but I feel that I must write it in my consciousness. First, this is a failure experience, I wrote a very bad program (day! That is also the program?). Worse, I can finally only give up the whole concept, and give up this attempt. The only result is that I wast a lot of time and get the very wonderful blow; second, from the feelings, I can't understand my failure, this It seems to be a simple problem, in the initial look, almost three hours, but I spent four days (except for eating sleep), the process made me really feel that "the moon myth" mentioned That taro, all my hard work just accelerated my sink. After four days of nightmare, my procedure is reasonable and sank to the bottom of the pit, and I have to accompany the ancient beast. I have never changed this almost the truth. The phenomenon, I am a "person" after all, this is the only comfort I can get, thank God!).
For this problem itself, I don't want to say more, it is simple to make a person who has learned a half year C easily to get it in one day, the full-text index is in the "C Primer" Chapter 6, the clear white , I also know that this book can be found in the place in my room, but I don't know if my brain has a problem. I actually believe that my 667MBHZ CPU can give each 1MB file within 1 second. The number of characters appeared, and then I made this ridiculous belief as a fact. Until I heard the call for the ancient beasts in love (thank them, let me understand why my program left this world),
There is no doubt that my program is built on a false assumption. The root cause is that I only spend 5 minutes in the overall design, and everything is carried out in the brain, and this brain has a beautiful magical dream, just like the coke pit as a swimming pool, I should understand why In a software design process, the encoding only has one-sixth time, in fact, this thing does not have the theory of software engineering. Anything that is not prepared will not have any good results. But we often forget this, tragedy often come.
Sometimes I have been thinking, why can't I always have a key to the key? Is there anything less than my thinking? Or do you overlooked in the past? In this trial, it is obvious that I have no feelings about the algorithm. This is not only the role of my ridiculous belief. I have always thought that the assetwork is the basis of the data structure, from this point I did it. This makes I have to go on the handling of the file, but I forgot the other plus of the well-known equation (program = data structure algorithm), blind search makes the complexity of the program turn about 50 Double, the selection of data structures cannot be adapted to the later improvements to the algorithm, making my efforts in document processing in vain, I don't know that equation? Of course not. My mistake is to think about the data structure and consider the algorithm, and in fact, the prior contrary, the better data structure can only be used for a particular algorithm. That is to say, the data structure algorithm has been self-cleaned, there is no big choice, when you find this algorithm, then you will have a big improvement, so well, the nightmare begins!
