### Prompt

Construct a Cpp code solution to the problem outlined:

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.

using namespace std;

LL calc(LL x, LL n){
    LL ans = 1;
    while(n > 0){
        if(n & 1){
            ans = ans * x % MOD;
        }
        x = x * x % MOD;
