Given a list of movies in the cinema. Starting with index 0, each element in the array is the name of the movie in production on the i-th day. Transform this data by creating a dictionary schedule that for each movie as key stores the list of days when this movie screenings are. For example:

movies = ['Shrek', 'Snow White', 'Cars', 'Cars', 'Shrek', 'Shrek 2'] =>

schedule = {
    'Cars': [2, 3],
    'Shrek': [0, 4],
    'Shrek 2': [5],
    'Snow White': [1]
}

Remember about case if movie is not in dict already.
