题解 | 单组_spj判断YES与NO

import java.util.Scanner;
public class Main{
    public static void main(String[] args){
        Scanner sc  = new Scanner(System.in);
        int n = sc.nextInt();
        if(n%2 == 0){
            System.out.println("NO");
        }
        if(n%2 == 1){
            System.out.println("YES");
        }
        sc.close();
    }
}

没有任何逻辑，直接让K和n-1进行比较
