first J students, I, J difference not more than D, so that can meet the requirements of the topic. The auxiliary amount F (i,k) is not the final result we are going to get, the final result of opt (i,k) is to select the maximum number of K students among the first I students, so the relationship between opt (i,k) and F (i,k) can be: The second key point of the problem is that the student's ability value is between 50 and +50, and each student's ability value is positivel
dangerous to know half the solution (a little learning is a dangerous thing) C ++: In three days, you can learn the C ++ syntax (if you already have a similar language), but you cannot learn how to use it. In short, if you are, for example, a basic programmer, you can learn to write a basic-style program in C ++ syntax, but you cannot learn the true advantages (and disadvantages) of C ++ ). Where is the key? Alan Perlis (first Chairman of ACM, winn
needs to have the support of mathematical knowledge;3. Many computer programming languages are critical to English;4. Computer programming requires language is nothing logical thinking, so it is necessary for the programmer to join the logical thinking;Analysis of the characteristics of computer language, we will be transformed into self-learning when the corres
Many people in the technology alliance asked me how to learn various programming languages. Of course, everyone has a learning method. I personally think that your interest in doing anything will determine your motivation for learning, from ASP to PHP to JAVA Development, I learned all the way and found that programming
One: Cause(0) Perhaps because of a momentary impulse you start to focus on and learn shell programming, but also because the "hearsay" shell is very powerful, but also because of the charm of shell programming, but also because as a coder of the preferences, also Xu ...(1) First to figure out why to learn the shell, learning to be purposeful----simply saying that
I seldom review my source motivation, methods, and habits for learning. According to the author of "programming those things", a part of thinking is in an unactivated stage, or, as another author says, thinking enters the comfort zone for the environment or well-known things, and imperceptible. When talking about the comfort zone, you can refer to this blog: Can the thoughts of adults be improved? Hand-cook

Python standard library is really huge. It can help you with all kinds of work, including regular expressions, document generation, unit tests, threads, databases, Web browsers, CGI, FTP, e-mail, XML, XML-RPC, HTML, WAV files, cryptography systems, GUI (graphical user interface), TK, and other system-related operations.6. Canonical code: Python uses forced indentation to make the code extremely readable.7. Scalability and embeddable. If you need a piece of your critical code to run faster or yo
Start with learning Python and learn Python programming. Through the study of the four arithmetic operations, we have initially come into contact with the content in Python. It may be a bit confusing if the reader is a zero-base learner. Do I have to write a few commands in IDE and then see the results? Isn't that a program that can run automatically? Indeed. So far, pr

the size of the state space is polynomial, then the algorithm using dynamic programming is polynomial time, and the algorithm using dynamic programming is exponential time, assuming the size of the state space is exponential. Therefore, it is very important to find a good state partition for the efficiency of dynamic programming.5 Small experiment for change pro
这也是我第一接触函数式编程这个概念，并不知道是干嘛的？好奇心驱使下学习了一下，有了大致的了解：函数式编程自己的理解：就跟说话一样写程序，这个程序写出来可以直白的告诉人是要干嘛的。以下是我读到的关于函数式编程的文章的描述： One of the features of functional programming is that it allows the function itself to be passed as a parameter to another function, and also allows a function to be returned! [1] Functional programming Guidelines: Do not rely on external data, and do not change the value of external data,
