E - A^B mod C （大数乘方取模）

Description

Given A,B,C, You should quickly calculate the result of A^B mod C. (1<=A,B,C<2^63).

Input

There are multiply testcases. Each testcase, there is one line contains three integers A, B and C, separated by a single space.

Output

For each testcase, output an integer, denotes the result of A^B mod C.

Sample Input

3 2 4
2 10 1000

Sample Output

1
24
解题思路：直接调用BigInteger大数类中的modPow(n,m)方法即可，java简单水过！
AC代码：

import java.util.Scanner;
import java.math.BigInteger;
public class Main {
    public static void main(String[] args) {
        Scanner scan = new Scanner(System.in);
        while(scan.hasNext()){
            BigInteger a = scan.nextBigInteger();
            BigInteger b = scan.nextBigInteger();
            BigInteger c = scan.nextBigInteger();
            System.out.println(a.modPow(b,c));//大整数乘方和取模
        }
    }
}
