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_SqcrL):
Determine the value of f that satisfies: 144*f - 10 = 2582 Respond with an integer.

Question 1 (Question id: q_VUWSxfSK):
Calculate 7 + 1 + -6.

Question 2 (Question id: q_yU3d):
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 3 (Question id: q_L7uLqYF):
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: "things"



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

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

{"ground_truth": {"q_SqcrL": {"answer": 18, "answer_type": "integer", "additional_answer_info": {"half_answer": 9, "double_answer": 36}}, "q_yU3d": {"answer": "r", "answer_type": "string", "first_char": "r", "original_string": "for"}, "q_L7uLqYF": {"answer": "s", "answer_type": "string", "first_char": "s", "original_string": "things"}}}
