HasDuplicateValue

Language/Type: C# Dictionary collections

Write a method named HasDuplicateValue that accepts a SortedDictionary 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 HasDuplicateValue(m) would return true because both "Jessica" and "Meghan" map to the value "Miller". Return false if passed an empty or one-element map. Do not modify the dictionary passed in.

Method: Write a C# method as described, not a complete program or class.
