代码如下：

import java.util.Scanner;

public class Main {

    public static void main(String[] args) {
        // TODO Auto-generated method stub
        Scanner input = new Scanner(System.in);
        String str = input.nextLine();
        String[] strArr = str.split(" ");
        for(int i=0;i<strArr.length;i++){
            if(i==(strArr.length-1)){
                System.out.print(strArr[strArr.length-i-1]);
            }else{
                System.out.print(strArr[strArr.length-i-1]+" ");
            }
        }
    }
}
