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.util.Scanner;

public class Exer1028B {
	public static void main(String[] args) {
		
		Scanner in = new Scanner(System.in);
		int n = in.nextInt();
		int m = in.nextInt();
		in.close();
		
		StringBuilder a = new StringBuilder();
		StringBuilder b = new StringBuilder();
		int rank = n / 9 + 2;
		for(int i = 0; i < rank; ++i) {
			a.append("9");
		}
		for(int i = 0;i<rank;++i) {
			a.append("0");
			b.append("9");
		}
		a.deleteCharAt(a.length() - 1);
		a.append("5");
		b.deleteCharAt(b.length() - 1);
		b.append("5");
		System.out.println(a);
		System.out.println(b);
