Output示例
537643802472代码如下:
import java.util.Scanner;
import java.math.BigInteger;
public class pp
{
public static void main(String[] args)
{
String s1,s2;
Scanner cin = new Scanner(System.in);
s1 = cin.next();
s2 = cin.next();
BigInteger b1 = new BigInteger(s1);
BigInteger b2 = new BigInteger(s2);
System.out.println(b1.add(b2));
cin.close();
}
}
乘法代码示例:
import java.util.Scanner;
import java.math.BigInteger;;
public class pp
{
public static void main(String[] args)
{
String s1,s2;
Scanner cin = new Scanner(System.in);
s1 = cin.next();
s2 = cin.next();
BigInteger b1 = new BigInteger(s1);
BigInteger b2 = new BigInteger(s2);
System.out.println(b1.multiply(b2));
cin.close();
}
}
