       str += " "; 
       String word = "", lWord = "", sWord = str;
       int len = str.length();
       
       for (int i = 0; i < len; i++) {
           char ch = str.charAt(i);
           if (ch == ' ') {
               
                if (word.length() > lWord.length())
                    lWord = word;
                else if (word.length() < sWord.length())
