Problem: Let s(x) be sum of digits in decimal representation of positive integer x. Given two integers n and m, find some positive integers a and b such that 

  * s(a) ≥ n, 
  * s(b) ≥ n, 
  * s(a + b) ≤ m. 

Input

The only line of input contain two integers n and m (1 ≤ n, m ≤ 1129).

Output

Print two lines, one for decimal representation of a and one for decimal representation of b. Both numbers must not contain leading zeros and must have length no more than 2230.

Examples

Input

6 5


Output

6 
7


Input

8 16


Output

35 
53

Note

In the first sample, we have n = 6 and m = 5. One valid solution is a = 6, b = 7. Indeed, we have s(a) = 6 ≥ n and s(b) = 7 ≥ n, and also s(a + b) = s(13) = 4 ≤ m.

Solution (in JAVA):

Solution:
import java.util.Scanner;

public class Main {
    public static void main(String[] arg) {
        Scanner scan = new Scanner(System.in);

        int n = scan.nextInt();
        int m = scan.nextInt();

        StringBuilder num1 = new StringBuilder();
        StringBuilder num2 = new StringBuilder();
        for(int i = 0; i < 1115; i++) {
            num1.append(9);
        }
        for(int i = 1115; i < 2229; i++) {
            num1.append(0);
            num2.append(9);
        }

        num1.append(1);
        num2.append(9);


        System.out.println(num1.toString());
        System.out.println(num2.toString());
    }
}
