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: Accepted)

import java.util.Scanner;

public class Main{

	public static void main(String[] args)
	{
		@SuppressWarnings("resource")
		Scanner sc = new Scanner(System.in);

		while(sc.hasNext())
		{
			String[] s = sc.nextLine().split("[\\s]+");
			int value = Integer.parseInt(s[0]);
			int value_2 = Integer.parseInt(s[1]);
			int sum = value + value_2;
			int count = 1;
			while(sum / 10 != 0)
			{
				sum /= 10;
				count++;
			}
			System.out.println(count);
		}
	}
