Every Member's Clubs

A sign-up sheet records (name, club) tuples, one per sign-up. Some students signed up for the same club twice by mistake.

Write clubs_by_member(signups) that returns a dictionary of each student's name to a sorted list of their clubs, with no repeats.

An empty sheet gives an empty dictionary.

Examples

signups = [('ada', 'drama'), ('bo', 'chess'), ('ada', 'chess'), ('ada', 'drama')]

returns {'ada': ['chess', 'drama'], 'bo': ['chess']}

signups = [("cy", "art"), ("bo", "music"), ("cy", "music"), ("bo", "music")]

returns {'cy': ['art', 'music'], 'bo': ['music']}

signups = []

returns {}
