import java.util.Scanner;

public class Main {
    public static void main(String[] args) {
        Scanner scanner = new Scanner(System.in);
        double height = scanner.nextDouble();
        double weight = scanner.nextDouble();
        double bmi = weight / (height * height);
        //write your code here......
        String desc = (bmi < 18.5?"偏瘦":(bmi<20.9)?"苗条":(bmi<=24.9)?"适中"
        :"偏胖");
        System.out.println(desc);
        
    }
}

三目运算符的写法！！
