### Prompt

In Cpp, your task is to solve 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

5 8


Output

390625

### Response

```cpp
#include <iostream>
using namespace std;
const int MOD = 1000000007;

long long func(long long x, long long y) {
    if (y == 0) return 1;
    if (y % 2 == 0) {
        return func(x * x % MOD, y / 2);
    } else {
        return x * func(x, y - 1) % MOD;
    }
}

int main() {
    int m, n; cin >> m >> n;
    cout << (func(m, n) % MOD) << endl;
}
