Virtual contest is a way to take part in past contest, as close as possible to participation on time. It is supported only ICPC mode for virtual contests.
If you've seen these problems, a virtual contest is not for you - solve these problems in the archive.
If you just want to solve some problem from a contest, a virtual contest is not for you - solve this problem in the archive.

standard outputLet $$$s(x)$$$ 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

- $$$s(a) \ge n$$$,
- $$$s(b) \ge n$$$,
- $$$s(a + b) \le m$$$.

Input

The only line of input contain two integers $$$n$$$ and $$$m$$$ ($$$1 \le n, m \le 1129$$$).

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 $$$2230$$$.

Note

In the first sample, we have $$$n = 6$$$ and $$$m = 5$$$. One valid solution is $$$a = 6$$$, $$$b = 7$$$. Indeed, we have $$$s(a) = 6 \ge n$$$ and $$$s(b) = 7 \ge n$$$, and also $$$s(a + b) = s(13) = 4 \le m$$$.
