Write a method called numUnique that takes three integers as parameters and returns the number of unique integers among the three. For example, the call numUnique(18, 3, 4) should return 3 because the parameters have three different values. By contrast, the call numUnique(6, 7, 6) should return 2 because there are only two unique numbers among the three parameters: 6 and 7.
