import java.io.InputStreamReader;

public class onecode {

public static void main(String[] args) throws IOException

{

BufferedReader strin=new BufferedReader(new InputStreamReader(System.in));

System.out.print(“请输入一个字符串：”);

String str = strin.readLine();

String array[]=str.split(” “);

String printout=”“;

for(String item:array)

{

printout=item+” “+printout;

}

System.out.println(printout);
