import java.util.Scanner;

public class Demo{
	public static void main(String[] args){
		int chicken,rabbit;
		int H,Y;
		Scanner input=new Scanner(System.in);
		System.out.println("请输入鸡和兔的总头数");
		H=input.nextInt();
		System.out.println("请输入鸡和兔的总脚数");
		Y=input.nextInt();
		for(chicken=1;chicken<Y/2;chicken++){
			for(rabbit=1;rabbit<Y/4;rabbit++){
				if(chicken+rabbit==H && chicken*2+rabbit*4==Y){
					System.out.println("鸡的数量为"+chicken+"只，"+"兔的数量为"+rabbit+"只。");
					}
				}
			}
		}
