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 PYTHON):

Solution:
import sys, math
from sys import stdin, stdout
rem = 10 ** 9 + 7
sys.setrecursionlimit(10 ** 6+5)
#from resource import *; setrlimit(RLIMIT_STACK, (RLIM_INFINITY, RLIM_INFINITY))
take = lambda: map(int, stdin.readline().strip().split())
from bisect import bisect_right,bisect_left


n,m=take()
a=[0]*(2000)
b=[0]*(2000)
for i in range(1,2000):
    a[i]=1
    b[i]=8
b[-1]=9
a=int(''.join(map(str,a)))
b=int(''.join(map(str,b)))
print a
print b
