"(Service )" Given a non-empty list of words, return the k most frequent components. Your response should be sorted by regularity from greatest to cheapest. Amazon's designers therefore require to be able to create systems that are extremely scalable. The coding inquiries we have actually covered above generally have a solitary optimum solution.
