Here is a set of basic questions producing integer or string outputs. Answer them and format the result precisely with the JSON instructions provided:

Question 0 (Question id: q_18FE):
Calculate ( ( 0 * 5 ) ) * -4.

Question 1 (Question id: q_q3R84lJ):
Calculate 8 - -7 - -2.

Question 2 (Question id: q_HLMN):
How many times does the letter "c" appear in the text: "a defect"? Respond with an integer.



Your output must be a JSON mapping every question id to its answer info.

Each key’s value must be an object holding an 'answer' field.
Include an 'answer_type' field (value 'string' or 'integer') for every answer object.
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).
If the response to a question is a string, add a 'first_char' field containing its first character.
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' should equal the total questions that appeared.
• questions_with_integer_answers: ids of questions with integer replies.

Now provide the result JSON using the described format.
