#include<iostream>
using namespace std;

const int mod = 1e9 + 7;

int modpow(long long a, long long b){
    if(b == 0) return 1;
    if((b & 1) == 0) return modpow(a*a % mod, b/2);
    return a * modpow(a, b-1) % mod;
}

int main(){
    int a, b; cin >> a >> b;

}

### 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

Input

5 8


Output

390625

### Response

```cpp

#include<iostream>
using namespace std;

const int mod = 1e9 + 7;

int modpow(long long a, long long b){
    if(b == 0) return 1;
    if((b & 1) == 0) return modpow(a*a % mod, b/2);
    return a * modpow(a, b-1) % mod;
}

int main(){
    int a, b; cin >> a >> b;
    
    cout << modpow(a, b) << endl;
}

```
