### 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

8


Input

5 8


Output

390625

### Response

```cpp
#include<iostream>
#include<cstdio>
using namespace std;

long long pow(long long m,long long n)
{
	long long res;
	if(n==0) return 1;
	res=pow(m*m%1000000007,n/2);
	if(n%2==1) return res*m%1000000007;
	return res;
}

int main()
{
	long long m,n;
	
	cin >> m >> n;
	
	cout << pow(m,n) << endl;
	
	return 0;
}
```
