The winner of a fastest-code challenge is determined by the runtime performance of the submissions. For fairness, all submissions should be benchmarked on the same machine, which usually means all submissions have to be tested by the host of the challenge. Alternatively, the submission can be compared to a reference program. For scoring by asymptotic time complexity, use [fastest-algorithm] instead.
