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.
import java.io.IOException;
import java.util.Scanner;

public class Main {

    public static void main(String[] args) throws IOException {
	Scanner in = new Scanner(System.in);
	int n = in.nextInt(), m = in.nextInt();
	StringBuilder s1 = new StringBuilder(), s2 = new StringBuilder();
	for (int i = 0; i < 1000; i++) {
	    s1.append("5");
	    s2.append("4");
	}
//	56
//	44
	s1.append("6");
	s2.append("4");
	System.out.println(s1.toString());
	System.out.println(s2.toString());
    }
