### Prompt

Generate a CPP solution to the following problem:

For given integers m and n, compute mn (mod 1,000,000,007). Here, A (mod M) is the remainder when A is divided by M.

Constraints

* 1 ≤ m ≤ 100
* 1 ≤ n ≤ 109

Input


m n


Two integers m and n are given in a line.

Output

Print mn (mod 1,000,000,007) in a line.

Examples

Input

2 3


Output

8


Input

5 8


Output

390625

### Response

```cpp
#include <iostream>

using namespace std;

int main() {
  long long int m, n;
  cin >> m >> n;

  long long int res = 1;
  while(n > 0) {
    if(n & 1) {
      res *= m;
    }
    res %= 1000000007;
    m *= m;
    m %= 1000000007;
    n >>= 1;
  }

  cout << res << endl;

  return 0;
}
