### 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

Output

390625

### Response

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


const int MOD=1000000000+7;

ll f(ll m,ll n){
  ll cal=1;
  while(n>0){
    if(n&1){
      cal*=m;
      cal=cal%MOD;
    }
    m *= m;
    m =m%MOD;
    n >>= 1;
  }
  return cal;
}


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