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_tdIlEY):
Solve for f: 13 - 5*f = -22 Respond with an integer.

Question 1 (Question id: q_qLLIA):
Calculate ( 4 / 2 + -1 ).

Question 2 (Question id: q_xmEmYM):
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: "full"



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

The value for each key should be an object that contains the answer in the field 'answer'. 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.
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.

Now provide the result JSON using the described format.

{"ground_truth": {"q_xmEmYM": {"answer": "l", "answer_type": "string", "first_char": "l", "original_string": "full"}, "q_qLLIA": {"answer": 1, "answer_type": "integer"}}}
