This competition had one official technical issue and one technical issue from the organizer... It ruined the first three very interesting questions. I feel very angry.

Divide the largest by the smallest each time, when there is a 1 in the array, it is not possible for all of them to be the same. I guess it for 1.5h. I don't think it's a great problem.
