Given two integers low and high representing a range, return the sum of the integers in that range. For example, if low is 12 and high is 18, the returned values should be the sum of 12, 13, 14, 15, 16, 17, and 18, which is 105. If low is greater than high, return 0. Examples:

sumRange(12, 18) -> 105

sumRange(1, 5) -> 15

sumRange(1, 100) -> 5050

       System.out.println(sumRange(12, 18)); // prints 105

       System.out.println(sumRange(18, 12)); // prints 0

       System.out.println(sumRange(18, 18)); // prints 18

   }

   public static int sumRange(int low, int high)

   {

       int sum = 0;

       for (int val = low; val <= high; val++){

           sum += val;

       }

       return sum;

   }

}

the only way i would see could be an autoclicker type software. but that is very time consuming.
