### 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.

### Response

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


int main(){
    long long m,n,ans=1;
    cin>>m>>n;
    while(n>0){
        if(n&1){           
            ans*=m;
        }
        m *=m;
        m%=1000000007;
        n >>= 1;
        ans = ans%1000000007;
    }
    cout<<ans<<endl;
}
