Java实现：
import java.util.*;
import java.math.*;
public class Test{
public static void main(String args[]){
Scanner sc = new Scanner(System.in);
BigInteger a, b;
while (sc.hasNext())
{
a = sc.nextBigInteger();
b = sc.nextBigInteger();
System.out.println(a.add(b)); //大整数加法
System.out.println(a.subtract(b)); //大整数减法
System.out.println(a.multiply(b)); //大整数乘法
System.out.println(a.divide(b)); //大整数除法(取整)
System.out.println(a.remainder(b)); //大整数取模
}
}
}
