You are given two int variables j and k, an int array zipcodeList that has been declared and initialized, an int variable nZips that contains the number of elements in zipcodeList, and an int variable duplicates. Write some code that assigns 1 to duplicates if any two elements in the array have the same value, and that assigns 0 to duplicates otherwise. Use only j, k, zipcodeList, nZips, and duplicates.
