has_duplicate_value

Language/Type: Python dict collections

Write a function named has_duplicate_value that accepts a dictionary from strings to strings as a parameter and returns True if any two keys map to the same value. For example, if a dictionary named m stores {'Marty': 'Stepp', 'Stuart': 'Reges', 'Jessica': 'Miller', 'Amanda': 'Camp', 'Meghan': 'Miller', 'Hal': 'Perkins'}, the call of has_duplicate_value(m) would return True because both 'Jessica' and 'Meghan' map to the value 'Miller'. Return False if passed an empty or one-element dictionary. Do not modify the dictionary passed in.

Function: Write a Python function as described, not a complete program.
