### Prompt

Your task is to create 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 <iostream>
using namespace std;
typedef long long ll;
const ll mod = 1000000007;

ll power(ll x,ll n){
  if(!n) return 1;
  ll res = power(x * x % mod , n / 2);
  if(n & 1) res = res * x % mod;
  return res;
}

int main(){
  ll m,n;

  cin >> m >> n;
  cout << power(m,n) << endl;

  return 0;
}
```
