### Prompt

Please formulate 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

### Response

```cpp
#include<iostream>
#define MOD 1000000007LL
typedef long long ll;
using namespace std;
ll pow(ll m, ll n){
  if(n==1){
    return m;
  }
  ll a=pow(m,n/2);
  a =a*a%MOD;
  if(n%2==1){
    a=a*m%MOD;
  }
  return a;
}

int main(){
  ll m,n;
  cin >> m >>n;
  cout<< pow(m,n)<<endl;
  return 0;
}
