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_tOtHM):
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: "of"

Question 1 (Question id: q_Hyse):
Calculate 1 - -1.

Question 2 (Question id: q_kf50):
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 2 sheeps, 4 dogs, 4 ants, 3 snakes?
 Respond with an integer.



Return a JSON with each question id as a key.

The value for each key should be an object that contains the answer in the field 'answer'.
Include an 'answer_type' field (value 'string' or 'integer') for every answer object.
For even integer answers, include 'half_answer' equal to answer ÷ 2.
For string answers, include 'first_char' with the answer’s initial letter.
For last-character tasks, provide 'original_string' alongside the answer.

Now provide the result JSON using the described format.
