#include <iostream>
using namespace std;
typedef long long ll;
const int MOD = 1000000007;

ll modPow(ll m, ll n) {
    if (n == 0) return 1; 
    if (n % 2) return m * modPow(m, n-1) % MOD;
    else modPow(m * m % MOD, n / 2);
}

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

### 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

2 3


Output

8


Input

### Response

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

ll modPow(ll m, ll n) {
    if (n == 0) return 1; 
    if (n % 2) return m * modPow(m, n-1) % MOD;
    else modPow(m * m % MOD, n / 2);
}

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