TopCoder Arena is a famous online competition for programmers to demonstrate their talent in algorithm and programming. There are many talent people participated in it, and the competition time is not enough at all for most participators. You have to translate the problem description into the C++ class and method, design the algorithm, implement, and test them manually. Now with TopCoder AutoGen, what you need to do is to design the algorithm to resolve the problem only, and AutoGen will handle anything else. TopCoder AutoGen will help you focus your attention on the problem themselves by generating a pure C++ programming and test framework automatically, and help you win the arena in the limited competition time. You can copy the problem, and paste into it, click the generate button. It will then generate the C++ framework for you and copy to the clipboard directly. It is very easy to use, and saves up to 30% of your time.
