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.

Input

m n

Two integers m and n are given in a line.

Output

Print mn (mod 1,000,000,007) in a line.

Constraints

1 ≤ m ≤ 100

1 ≤ n ≤ 109

Solution in JAVA (judge verdict: Wrong Answer)

import java.util.*;

public class Main {

	public static void main(String[] args) {
		Scanner in=new Scanner(System.in);
		long m=in.nextLong(),n=in.nextLong(),d=1000000007;
		long a=m;
		for(int i=2;i<=n;i++)a*=m;
		System.out.println(a%d);
	}
