  Import java.io.*;  public class Exercise {public      static void Main (string[] args) throws IOException {                  BufferedReader reader = new Bu Fferedreader (New InputStreamReader (system.in));//input         String str = reader.readline ();                  char Chararray;         for (int i =0;i<str.length (); i++)//output character         {            chararray= (char) (Str.charat (i));             if ((chararray>=65&&chararray<=87) | | | (chararray>=97&&chararray<=119))             {                 Chararray + = 3;             }             else             {                 Chararray = (char) (CharArray-23);             }             System.out.print (Chararray);         }     } }
