I didn't know what to learn. I saw various languages and technologies in the library and on the Internet, and I don't know where to start. If someone does not know how to choose th

One TopCoder article introduces a very interesting alternative solution to longest Common sequences problem.It is based on this statement (http://community.topcoder.com/tc?module=Staticd1=tutorialsd2= stringsearching): The important point and allows us to use BS are the fact that if the given strings has a common substring of length n, th EY also has at least one common substring of any length m So we can start b-search on string length of S1

Transferred from: http://www.iteye.com/news/30801An article in Hacker News today, "why people who think slowly can win", has aroused extensive discussion."Before I hired a TopCoder champion, I expected him to code fast, but in fact he was the most careful and meticulous person, but we were gradually discovering that in two years, the code he submitted was never a bug and never was," said Burson, a netizen who commented on the article. ”Why does it see

If you want to understand whether you really know a certain knowledge, you can give it to others! When you are teaching to others, you must answer these questions that you may never have thought about before. by teaching them, what knowledge will be exposed! In addition, being a mentor to others will also establish a loyal network of relationships. There is no need to establish a formal relationship between teachers and students, and the benefits will naturally come along from helping others.

I heard that there is still topcoder in the world. Of course, this is not the best Oscar actor, but a programming competition, and it has a cash return. According to unreliable news, someone in China has received a prize of tens of thousands of dollars, $ o $. The ACM competition is similar to it, just like Lego building blocks. However, ACM is used to lay the foundation, and has to be able to withstand it. I made some questions and thought that the

The problem-solving report is about the upstream and downstream expense streams. I use the upstream and downstream methods here. The same is true without going through the upstream and downstream services. I will change the cost of passing through the edge to-inf, then, when the minimum fee flow is obtained, the program will pass through this edge and also play the role of limiting the lower bound, so as to better understand ~# Pragma comment (linker, "/STACK: 102400000,102400000 ")# Include # I

No one has said that there are two kinds of people in the world, one is a programmer, one is not. And more and more people find that programming ideas can be better and more efficient to accomplish tasks. The development of IT industry makes programmers tend to mass production, endless, and the Internet industry is also closely along with the development of a series of programmers contest.
