题解 | #交换变量值#

在不使用第三个变量的前提下 想到了加减乘除

import java.util.Scanner;

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;
        b = a / b;
        a = a / b;

        System.out.println(a+" "+b);
    }
}
