Who is smarter solution in java

 Who is smarter

Rahul and Rama are siblings. Rahul believes that he is smarter than Rama so Rama decides to teach him a lesson. She gives him 2 non-negative integers A and B and asks him to reverse the two numbers and tell the greater one.

If the numbers after reversing contain leading zeros, you have to ignore them. See the sample examples for better clarification.

Input Format

The only line containing 2 non-negative integers A and B.

Constraints

0 <= A, B <= 1000, 000, 000

Output Format

Print the answer to the problem.

Sample TestCase 1

Input

12 100

Output

21

Explanation

The numbers after reversing becomes 21 (12) and 1 (001). Clearly, 21 is bigger.

Sample TestCase 2

Input

100 100

Output

1

Explanation

Both of the numbers after reversing become 1. So, 1 is the answer.

           num2 = num2 / 10;
       }
       if(reverse1 > reverse2)
           System.out.println(reverse1);
       else
           System.out.println(reverse2);
  }
