Return a JSON with each question id as a key.

Each key’s value must be an object holding an 'answer' field. Additionally, if the task is about counting legs of animals or counting letters in a string, add the task_type field with value 'leg_counting' or 'letter_counting', respectively.
If the response to a question is an integer that is even, also add the field 'half_answer' to the object which contains the answer integer divided by two.
If the question asks for the last character of a string, add an 'original_string' field containing the source string.

Add a top-level 'global_metadata' field that records overall stats:
• num_questions_asked – total number of questions originally shown.

Also include 'combined_results' consisting of:
  • integer_info: per-id integer answers
  • sum_of_answers: their total

Now provide the result JSON using the described format.
