Problem

We run a short-video platform where the catalog of videos is small but views pile up fast, and we want to know which creators actually hold attention rather than just publish volume. Pair each view with its video's creator and, for each creator, report the total seconds watched and the number of views, keeping only creators whose videos drew more than 1000 total seconds of watch time. List the most-watched creators first.
