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 PYTHON3):

Solution:
tmp = list(map(int, input().split(' ')[:2]))
n = tmp[0]
m = tmp[1]
a = 6
b = 4
sum = 4
i = 1
mult = 10
while sum < n:
    if i%2:
        a += mult*4
        b += mult*5
        mult *= 10
        i += 1
        sum += 4
    else:
        a += mult*5
        b += mult*4
        mult *= 10
        i += 1
        sum += 4
print(a)
print(b)
