Rules: - A word is a sequence of non-space characters separated by spaces. - If total words < 9 or total words is even (including empty or space-only strings), print a copy of the string followed by " \n". - If total words >= 9 and odd: 1. Replace 2nd word occurrences with case-flipped 6th word. 2. Replace 6th word with original 2nd word. 3. Insert (total_words + 2) after the middle word. 4. Print transformed string followed by " \n".
