Pregunta de entrevista de C3 AI

4 questions were asked, 3 multiple choice machine learning based questions. One was coding an algorithm. The coding interface was not that easy to debug in (I'd suggest you try a few Hackerrank questions first, I tried the sample one but I never had to debug so I didn't realise) and I couldn't output the answer in the needed format but on my IDE I got a correct answer.
