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_35fBT):
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: "that"

Question 1 (Question id: q_lhvz):
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 humans, 1 lion, 4 jellyfishs, 2 starfishs, 4 ants?
 Respond with an integer.

Question 2 (Question id: q_yKWHA):
Determine the value of u that satisfies: 44*u + 5 = 841 Respond with an integer.



Produce a JSON object whose top-level keys are the question ids.

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.
If the response to a question is an integer that is even, also add the field 'half_answer' to the object which contains the answer integer divided by two.
If the response to a question is a string, add a 'first_char' field containing its first character.

Now provide the result JSON using the described format.
