About

AtCoder is a programming contest website based in Japan. AtCoder is a programming contest site for anyone from beginners to experts. We hold weekly programming contests online. Every AtCoder users can use this library with minimum efforts of studying about PC. Maximize convenience for the usage in competitive programming. We completely ignore other usages. Participants can use any programming language used in AtCoder Regular Contest. Unless otherwise specified, you must compete in a contest alone. We do not allow you to team up form with others. The contestant who gives successful solutions to the largest number of problems in a given time will be the winner. If there are multiple contestants who have solved the same number of problems, whoever has done so in shorter time will be in the higher place. Execution time is measured as the maximum of real time and CPU time. Parallelization is not prohibited, but it does not lead to shorter execution time.

About

Achieve mastery through challenge. Improve your skills by training with others on real code challenges. Challenge yourself on kata, created by the community to strengthen different skills. Master your current language of choice, or expand your understanding of a new one. Solve the kata with your coding style right in the browser and use test cases (TDD) to check it as you progress. Retrain with new, creative, and optimized approaches. Kata are ranked to approximate difficulty. As you complete higher ranked kata, you progress through the ranks so we can match you with relevant challenges. Compare your solution with others after each kata for greater understanding. Discuss the kata, best practices, and innovative techniques with the community. Author kata that focus on your interests and train specific skillsets. Challenge the community with your insight and code understanding.
