### 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

### Response

```cpp
#include<bits/stdc++.h>
using namespace std;
#define mod 1000000007
using ll=long long;

ll power(ll n,ll m)
{
    ll ans=1;
    for (int r=0;m>>r>0;r++)
    {
        if ((m>>r)&1) ans=ans*n%mod;
        n=n*n%mod;
    }
    return ans;
}

int main()
{
    ll n,m;cin >> n >> m;
    cout << power(n,m) << endl;
    return 0;
}
