Kim also recently developed a "fourth-party software" that works with this section to use on Apple's Macintosh computers. The software runs on top of macpaint, including many exercises, techniques, and games used to create an "invert

easily repaired. 6. No good encryption measures were taken to protect data Sensitive data needs to be encrypted when being uploaded or transmitted over the Internet, because it is likely to be intercepted during this process. Don't complain. This is the most basic security requirement. This also means that it is not recognized to send data in plain text, and also does not eliminate our own encryption methods and obfuscation targets. It is difficult to write a secure encryption system-you can se

, what is the best career path? Joke. What do you think if I tell you that programmers can be divided into eight levels? 1. Immortal programmers:This is the highest level. You wroteCodeIt does not go with you, but is retained (Wan Gu liufang ). You will survive in the computer field. Other programmers will study your achievements and works. You may have received the Turing Award, published a paper with great influence, or invented one or more basic technologies known to everyone, which has

you can quickly create models and think about new algorithms. This requires more comprehensive questions at ordinary times.1. Take a look at the papers on oibh (about a few hundred articles, I only read a little bit, huh, huh ).2. Scan the problems on zoj at ordinary times. Don't always do things that you don't need to think about. (The moderators of ACM often say that I can do it simply:-P)3. participate in online competitions, feel the competition atmosphere, and evaluate your strength.4. If

not consider minor performance improvements. optimization should be a 97% Performance Improvement: Early optimization is the root of all evil,"-Donald knuth. Code reuse-This is not a very core principle, but it is as valuable as other principles. Code reuse can improve program reliability and save your development time. Separation of duties-Functions in different fields should be managed by completely diff

However, if this algorithm repeatedly checks 25 reportsNIt may be a prime number, so we can sayN"It is almost certainly a prime number ". This is because the probability of an error message about its input is less than (1/4) 25 in such a 25-time test process. This opportunity i

, they thought they knew and said it would take at least three months to fully implement the features required by the customer.Young programmers have not experienced so many such situations, so they seldom resist the wrong decisions of managers. Managers cannot use their naive ideas to ask for things. If you want to have a good team and make it produce excellent products, allowing people to pull you back from the wrong path will save your project again and again. Of course, this is only true if

first round of sorting, the interval for the second trip to N/4, and so on. However, practice has shown that such a method sometimes reduces the execution time to O (N2). is no more efficient than inserting a sort. It is important to keep the number coprime in the interval sequence, that is, they do not have a convention number other than 1. This constraint is not followed when simply taking the interval to n/2,n/4,n/8...1, so the efficiency of the hill sort is reduced. There are ver

String matching is one of the basic tasks of a computer.For example, there is a string "BBC Abcdab Abcdabcdabde", and I want to know if it contains another string "Abcdabd"?Many algorithms can accomplish this task, and the Knuth-morris-pratt algorithm (abbreviated KMP) is one of the most common. It was named after three inventors, and the first K was the famous scientist Donald Knuth.This algorithm is not e

corresponding performance tuning strategy. 1.2 Rules for tuning We just need to be concerned about the performance issues that affect our programs, and what we perceive, rather than each of the methods in each class, we need to do something to improve performance. If the performance of the program does not meet the requirements we expect, we need to consider how to optimize performance. Similarly, obscure code can improve the performance of the program, but at the same time it may bring us a
