public class Main {
public static void main(String[] args) {
Scanner scanner = new Scanner(System.in);
int a = scanner.nextInt();
int b = scanner.nextInt();
//write your code here.......
a=a^b;// 按位与就是一种对称加密 a^b^b = a， a=a^b 保存了两个数字的信息，分别提取出来
b=a^b;// b=a^b^b = a
a=a^b;// a=a^b^a = b
System.out.println(a+" "+b);
