### 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

Output

390625

### Response

```cpp
#include <iostream>

using namespace std;
typedef unsigned long long ll;

const ll M = 1000000007;

ll power(ll x, int n)
{
    if(n == 0) return 1;
    if(n%2 == 0) return power((x*x) % M, n/2) % M;
    if(n%2) return (power((x*x) % M, n/2) * x) % M;
}

int main()
{
    ll x;
    int n;
    cin >> x >> n;
    cout << power(x, n) << endl;
}
