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

int main(){
	ios::sync_with_stdio(false);
	cin.tie(0);
	const long long mod = 1000000007;  
	long long m, n;
	cin >> m >> n;
	long long ans = 1;
	while(n > 0) {
		if(n & 1) {
			ans = ans * m % mod;
		}
		m = m * m % mod;
		n >>= 1;
	}
	cout << ans << endl;
	return 0;	
}
