No one has said that there are two types of people in the world. One is a programmer, and the other is not. More and more people are making use of programming ideas to better and more efficiently complete tasks. With the development of the IT industry, programmers tend to produce mass data, and the Internet industry is also closely following the development of a series of programmer competitions. Algorithm Competition This type of competition really considers a programmer's programming philosoph

The Java Interface Programming and algorithm analysis were browsed within one week. Today's topcoder exercises are not made. In summary, we think too much, too complicated, and always want the optimal solution. The top priority of software is to work out, and then the efficiency problem. Remember. When an algorithm problem occurs, split the idea in the first step, and directly solve or contact the previous questions in the second step. Step 3: make

it. All topcoder programming languages can simulate the operation of deleting a character within a constant time instead of creating an original string or moving other characters. Addword (vertex, word) Countwords and countprefixes functions are similar. If we look for an empty string, we only need to return the number of words or prefixes associated with this node. If we are looking for a non-empty string, we should look for a corresponding subtree

topcoder. Although the two websites also provide the ability to view code, in contrast, I think this website is more like an OJ, which gives us a kind of intimacy with those who are used to OJ. Project Euler There are a lot of math problems in this website. If you like mathematics, you may wish to take a look. Algorithm notes This website is my favorite, although it is traditional. The name is like an algorithm note. MathschallengeProject Euler is

. In addition, there are many desktop programs, games using Python as the scripting engine. Ruby: It seems like the main use of Ruby on Rails for web development. ask yourself a self-answer Senior, this question is a freshman time asked, we only see the question I ask questions, do not know my motives behind the question, the reason for this problem is because at that time just into the university, very confused, do not know what to learn, in the library and online to see a variety of language t

Design Tutorial: Inverse the Problemtime limit per test2 secondsmemory limit per test256 megabytesinputstandard inputoutputstandard output There is an easy way to obtain a new task from an old one called "Inverse the problem": we give an output of the original task, and ask to generate an input, such that solution to the original problem will produce the output we provided. the hard task of Topcoder

Nyoj 585 stone (6) [Nim], nyojnim Stone (6) Time Limit: 1000 MS | memory limit: 65535 KB difficulty: 3 Description Recently, the PIAOYI and HRDV of TopCoder were boring, so I thought of a game. The game was like this: There were n piles of stones, and two people took turns to take some stones from one of them, the last one cannot be the loser. Note: You can only get any one from the heap at a time. You can get the heap, but you cannot can

developer. Software development means solving problems. If there is no problem, no software is required. All software is designed to solve certain user problems, and a general solution is an array of many small-scale problems that can be addressed. If you cannot solve the problem, you will not be proficient in software development, and the programming language or technology you use will not matter. When solving the problem, the performance of most developers is terrible. I often hear

lot of preparations for my future development, but I didn't help my mentor do anything. Therefore, I am grateful and embarrassed when I leave my master's degree. Another thing is to know Chen huaixing, a fellow in the same lab. Strictly speaking, he first came to chat with me. It can be seen that at that time I still did not realize the importance of communicating with others. Later, after establishing a toplanguage discussion group, I became more aware of the importance of communicating with

I leave my master's degree. Another thing is to know Chen huaixing, a fellow in the same lab. Strictly speaking, he first came to chat with me. It can be seen that at that time I still did not realize the importance of communicating with others. Later, after establishing a toplanguage discussion group, I became more aware of the importance of communicating with others and began to actively seek and participate in communication. I hope that I can organize communication in the future. Chen huaixi

As we all know, it is very efficient to search for ordered sequences using the bipartite method. In addition, the idea of the Bipartite method is applied in many aspects, not only to find a specific data. For example, when we evaluate the zero point of a monotonic function f (x), suppose we know that its zero point is in a range (a, B, then we can use the bipartite method to obtain the root of f (x) = 0. Now, let's look at a practical application. Topcoder
