抱歉，看錯，下面是java版:
/** *?Main.java */import?java.util.Scanner;
public?class?Main?{
public?Main()?{}
public?static?void?main(String[]?args)?{
Scanner?reader?=?new?Scanner(System.in);
while?(reader.hasNext())?{
String?s?=?sc.next();
s?=?Main.decodes(s);
System.out.println(s);
}
}
public?static?char?decode(char?ch)?{
int?ich?=?ch;
if?(ich?>=?'A'?&&?ich?<=?'W')?{
ich?+=?3;
}?else?if?(ich?>=?'X'?&&?ich?<=?'Z')?{
ich?+=?(3-26);
}
return?(char)?ich;
}
public?static?String?decodes(String?str)?{
StringBuffer?sb?=?new?StringBuffer(str);
for?(int?i=0;?i<str.length();?i++)?{
sb.setCharAt(i,?Main.decode(sb.charAt(i)));
}
str?=?sb.toString();
return?str;

}
