#include <bits/stdc++.h>
using namespace std;

#define MOD 1000000007

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

  int ans = 1;
  while(n > 0){
    if(n & 1 == 1) ans = (long long)ans * m % MOD;
    m = (long long)m*m % MOD;
    n >>= 1;

  return 0;
}




### Prompt

Your challenge is to write 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

Output

390625

### Response

```cpp
#include <bits/stdc++.h>
using namespace std;

#define MOD 1000000007

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

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

  cout << ans  << endl;

  return 0;
}
