给用Java的开一下荒土

解题思路:

注意事项:

参考代码:

import java.util.Scanner;

public class Main {

public static void main(String[] args) {

Scanner scanner = new Scanner(System.in);

while (scanner.hasNext()) {

int x = scanner.nextInt();

int y = scanner.nextInt();

int f = Math.abs(x);

int g = Math.abs(y);

    if(f<=1&&g<=1)

System.out.println("yes");

else 

System.out.println("no");

        }

    }

}
