Produce a JSON object whose top-level keys are the question ids.

For every question id, supply an object whose 'answer' field stores the solution.
If the response to a question is an integer that is even, add the field 'additional_answer_info' containing 'half_answer' (answer ÷ 2) and 'double_answer' (answer × 2).
For string answers, include 'first_char' with the answer’s initial letter.

Add a top-level 'global_metadata' field that records overall stats:
• num_questions_asked: how many questions were asked in total.
• num_questions_answered – number you actually answered.

Now provide the result JSON using the described format.
