"(Service )" Provided a non-empty checklist of words, return the k most constant components. Your response should be arranged by regularity from highest to least expensive. Amazon's engineers as a result require to be able to design systems that are very scalable. The coding concerns we have actually covered above generally have a solitary optimal service.
