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

long long b,p,m=1000000007,rt=1;

int main() {
	cin>>b>>p;
	for (;p;p>>=1,b=b*b%m) if (p&1) rt=rt*b%m;
	cout<<rt<<'\n';
}

### 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

Output

8


Input

5 8


Output

390625

### Response

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

long long b,p,m=1000000007,rt=1;

int main() {
	cin>>b>>p;
	for (;p;p>>=1,b=b*b%m) if (p&1) rt=rt*b%m;
	cout<<rt<<'\n';
}
