import java.util.Scanner; // 注意类名必须为 Main, 不要有任何 package xxx 信息 public class Main { public static void main(String[] args) { Scanner in = new Scanner(System.in); String str = in.nextLine(); String regex = "[^0-9a-zA-z]{1,}"; String[] strs = str.split(regex); for(int i=0; i<strs.length; i++){ System.out.print(strs[strs.length-1-i]+" "); } } }
