Java Code 3 _ Two - digit " Reduced Subtracted Form " [Wipro Interview Question]

Java Code 3 _ Two - digit  " Reduced Subtracted Form " [Wipro Interview Question] 

Question:

Given a number , you are expected to find its two digit "Reduced Subtracted Form ( RSF) "

The RSF of a number can be found by concatenating the difference between its adjacent digits.

To find two - digit "Reduced subtracted form ( RSF )" , we need to continue this process till the resultant RSF is not a two digit number . 

example :

input number : 6928

(6 - 9) is 3 

(9 - 2) is 7

(2 - 8) is 6

so the reduced RSF of 6928 is 376

(3 - 7) is 4

(7 - 6) is 1

so the reduced RSF of 376 is 41

so the output :

376

41 

Note: 

input number >= 100 .

while concatenating the differences use the absolute value(non negative value).

Program:

package numsub;
import java.util.Scanner;
public class NumSub
{
    static int subtractor(int n)
    {
        int result=0,temp,temp1,diff,pow=1;
            while(n>9)
            {
                temp=n%10;
                temp1=(n/10)%10;
                diff=(temp<temp1)?(temp1-temp):(temp-temp1);//Math.abs(temp1-temp)
                result=result+diff*pow;
                pow*=10;
                n/=10;
            }
            return result;
    }
    public static void main(String[] args)
    { 
        Scanner cin=new Scanner(System.in);
        int n=cin.nextInt();
        if(n>99)
        {
           while(n>99)
           {
           n=subtractor(n);
           System.out.println(n);
           }
        }
        else
        System.out.println(n); 
    }
}

Output:
