Prep Problem - 35

In this problem, you should write one function named get_common_movies. This function should have one parameter, which you can assume will be a list of sets. Each set in the list will contain movie titles (strings) representing someones collection of movies that he or she owns. The function should return a set of all of the movies that all of the collections have in common. I recommend that you use one (or more) of the functions from the video on set operations. For instance, the code:

collections = [{'terminator', 'matrix', 'avengers'}, {'terminator', 'john wick'}, {'indiana jones', 'terminator'}]
result = get_common_movies(collections)
print(result)

Should print

{'terminator'}

And the code:

collections = [{'Sherlock', 'Mighty Ducks', 'T2', 'John Wick'},
               {'John Wick', 'Mighty Ducks', 'T3'},
               {'John Wick', 'Mighty Ducks'},
               {'Alita', 'John Wick', 'T2', 'Mighty Ducks'}]
result = get_common_movies(collections)
print(result)    

Should print

{'John Wick', 'Mighty Ducks'}

Make sure to include only the one function in your file. The gradescope tests will call the functions to test them. Name the program prep35.py. Make sure that gradescope gives you the points for passing the test case.
