2.Find top watchlisted movies among friends

1.Implement theAnalyzerclass so that itssolvermethod returns an array of thetop fourmovie titles that have been most often added to a watchlist by friends of a given user.

2.If thesolvermethod doesn't returntop fourmovies, it should return the best N number of movies up to 4, otherwise, it should return an empty list.
