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.
def getFirst(n):
    first = []
    while (n > 0):
        first.append(5)
        n -= 4 #heh
    return first
def getSecond(first):
    second = []
    for num in first:
        second.append(4)
    second[-1] = 5
    return second

def getString(list):
    ret = ""

    for num in list:
        ret += str(num)

    return ret

def main():
    line = input().split(" ")
    n = int(line[0])
    m = int(line[1])

    first = getFirst(n)
    second = getSecond(first)

    print(getString(first))
