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.io.BufferedReader;
import java.io.IOException;
import java.io.InputStreamReader;
import java.math.BigInteger;
import java.util.StringTokenizer;

public class Main {

    static StringBuilder ans1, ans2;
    static int n, m;

    public static void main(String[] args) throws IOException {
        FastReader read = new FastReader();
        StringBuilder out = new StringBuilder();
        ans1 = new StringBuilder();
        ans2 = new StringBuilder();
        n = read.nextInt();
        m = read.nextInt();
        ans1.append(5);
        for (int i = 0; i < 2000; i++) {
            ans1.append(5);
            ans2.append(4);
        }
        ans2.append(5);
        System.out.println(ans1);
        System.out.println(ans2);
    }
