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.

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.
