解题思路:

注意事项:

参考代码:

import java.util.Scanner;

public class Main {

public static void main(String[] args) {

   Scanner scanner = new Scanner(System.in);

   String string = scanner.nextLine();

   System.out.println(string.length());

  char ch[]= string.toCharArray();

  for(int i = 0;i< ch.length;i++) {

  System.out.print(ch[i] +" ");

  }

  System.out.println();

  for(int j = ch.length-1;j>=0;j--) {

  System.out.print(ch[j]);

  }

}

}
