// Java Program to Illustrate Dereference

// Importing required classes
import java.io.*;
import java.util.*;

// Main class
class GFG {

    // Main driver method
    public static void main(String[] args)
    {
        // Reading input from keyboard by
        // creating object of Scanner class
        Scanner sc = new Scanner(System.in);

        // Taking input for two integer variables
        int a = sc.nextInt();
        int b = sc.nextInt();

        // Calculating sum of two variables and storing the
        // value in sum variable
        int sum = a + b;

        //  Print and display resultant length
        System.out.println(sum.length);
    }
