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 CPP):

Solution:
#include <bits/stdc++.h>
using namespace std;
template <class T>
int size(const T &x) {
  return x.size();
}
const int INF = ~(1 << 31);
const double EPS = 1e-9;
const double pi = acos(-1);
template <class T>
T smod(T a, T b) {
  return (a % b + b) % b;
}
int main() {
  for (decltype(0) i = (0); i < (1000); ++i) cout << "45";
  cout << endl;
  for (decltype(0) i = (0); i < (999); ++i) cout << "54";
  cout << "55" << endl;
  return 0;
}
