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_Ky7WD):
Your job is to return the last character of a string as a string. For example, the last char of "hello" is "o". Return the last character of the following string: "for"

Question 1 (Question id: q_YmpPGf6Z):
Calculate -1 * -6.

Question 2 (Question id: q_mA8jm0N):
Calculate 7 + -4 - 1.



Return a JSON with each question id (except for q_Ky7WD) as a key.

For every question id, supply an object whose 'answer' field stores the solution.
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, also add the field 'half_answer' to the object which contains the answer integer divided by two.
For last-character tasks, provide 'original_string' alongside the answer.

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

Now provide the result JSON using the described format.
