输入一个整数，若为奇数则输出其平方根，否则输出其立方根。要求分别用单分支、双分支及条件运算实现java

单分支实现：

import java.util.Scanner;

public class Main {
    public static void main(String[] args) {
        Scanner sc = new Scanner(System.in);
        int num = sc.nextInt();
        
        if (num % 2 == 1) {
            System.out.println(Math.sqrt(num));
        } else {
            System.out.println(Math.cbrt(num));
        }
    }
}

双分支实现：

import java.util.Scanner;

public class Main {
    public static void main(String[] args) {
        Scanner sc = new Scanner(System.in);
        int num = sc.nextInt();
        
        if (num % 2 == 1) {
            System.out.println(Math.sqrt(num));
        } else if (num % 2 == 0) {
            System.out.println(Math.cbrt(num));
        }
    }
}

条件运算实现：

import java.util.Scanner;

public class Main {
    public static void main(String[] args) {
        Scanner sc = new Scanner(System.in);
        int num = sc.nextInt();
        
        String result = (num % 2 == 1) ? String.valueOf(Math.sqrt(num)) : String.valueOf(Math.cbrt(num));
        
        System.out.println(result);
    }
}
