Problem:
Digit Number

Write a program which computes the digit number of sum of two integers a and b.

Input

There are several test cases. Each test case consists of two non-negative integers a and b which are separeted by a space in a line. The input terminates with EOF.

Constraints

0 ≤ a, b ≤ 1,000,000

The number of datasets ≤ 200

Output

Print the number of digits of a + b for each data set.

Sample Input

5 7
1 99
1000 999

Output for the Sample Input

2
3
4

Solution in JAVA (judge verdict: Wrong Answer)

import java.io.IOException;

public class Main{
    public static void main(String[] a) throws IOException {
		int s1 = 0,s2 = 0,i= 0;
		String[] Set = new String[5];
		String[] stock = new String[5];
		String Input = null;
		java.io.BufferedReader in = new java.io.BufferedReader(new java.io.InputStreamReader(System.in));
		try{
			while((Input = in.readLine()) != null){
				stock = Input.split(" ");
				s1 = Integer.parseInt(stock[0]);
				s2 = Integer.parseInt(stock[1]);
				Set[i] = String.valueOf(s1 + s2);
				i++;
			}
			
		}catch(Exception e){
		}finally{
			System.out.println(Set[0].length());
			System.out.println(Set[1].length());
			System.out.println(Set[2].length());
		}
    }
}
