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();

        //write your code here......
        double x = weight/(height*height);
        String a = x<18.5?"偏瘦":x<20.9?"苗条":x<=24.9?"适中":"偏胖";
        System.out.print(a);

    }
}

这次使用的昨天看见的三目运算符
