超简单的题目，，，就是给2个16进制的数，将它们的和按10进制输出！

JAVA可以直接读取16进制的数！

import java.util.Scanner;

public class Main {

    public static void main(String[] args) {

        Scanner sc = new Scanner(System.in);

        while(sc.hasNext()){

            int a = sc.nextInt(16);

            int b = sc.nextInt(16);

            System.out.println(a+b);

        }

    }

}
