Extracting observations from values

You're given a sample of the Netflix dataset containing TV shows and their casts called tvshow_df. You want to learn which six actors have the most appearances.

However, the dataset only has one row per TV show, and multiple actors are listed in the cast column.

Transform the data so that for each TV show, every actor has a row. The number of appearances will be calculated for you.

The dplyr package has been pre-loaded for you.
