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_8XT1):
Solve for f: 13 - 5*f = -22 Respond with an integer.

Question 1 (Question id: q_6jyMn3py):
Your task is to count how many legs there are in total when given a list of animals.

Now, how many legs are there in total if you have 3 insects, 2 ants, 2 wasps, 4 spiders, 2 butterflys?
 Respond with an integer.

Question 2 (Question id: q_VtLgOTK5):
Your task is to count how many legs there are in total when given a list of animals.

Now, how many legs are there in total if you have 4 snakes, 3 butterflys, 3 ducks, 3 starfishs, 1 lion?
 Respond with an integer.



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. If a question involves animal-leg or letter counting, include 'task_type' set to 'leg_counting' or 'letter_counting'.
For even integers, nest 'half_answer' and 'double_answer' inside an additional 'additional_answer_info' field in the answer object.
If the response to a question is a string, add a 'first_char' field containing its first character.
For last-character tasks, provide 'original_string' alongside the answer.

Now provide the result JSON using the described format.
