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_j5olJE):
Calculate 1 - 1.

Question 1 (Question id: q_ujiLp):
Calculate ( ( -7 * -3 ) ).

Question 2 (Question id: q_rxUAGHP):
Solve for w: 26 - 3*w = 23 Respond with an integer.

Question 3 (Question id: q_I3Y9cL3):
How many times does the letter "f" appear in the text: "that if"? Respond with an integer.

Question 4 (Question id: q_xUJcR):
Calculate 9 + -8.



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

For every question id, supply an object whose 'answer' field stores the solution. 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.
Also add the answer type as 'string' or 'integer' to the field 'answer_type' for each 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).

Now provide the result JSON using the described format.
