import java.math.BigInteger; import java.util.Scanner; public class Main { public static void main(String[] args) { Scanner sc = new Scanner(System.in); int t = sc.nextInt(); BigInteger k = new BigInteger("10"); while(t-->0){ BigInteger x = new BigInteger(sc.next()); BigInteger p = new BigInteger(sc.next()); System.out.println(x.modPow(p, k)); } } }

直接通过BigInteger的快速快速幂取模modPow
