/* NOTES
   (1)   if (Counter==1) Min = Values;
         else if (Values < Min) Min = Values;

         = statements in Pascal as :

         IF (Counter=1) THEN Min := Values
         ELSE IF (Values < Min) THEN Min := Values;

   (2)   ((Values % 2)==0)? Even = Even + 1 : Odd = Odd + 1;

         is a conditional expression, which equals to the following linea :

            if ((Values % 2)==0) Even = Even + 1;
            else Odd = Odd + 1;
