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_RHfV5t3f):
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: "to"

Question 1 (Question id: q_AW8u5):
How many times does the letter "f" appear in the text: "of 800"? 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'.
Also add the answer type as 'string' or 'integer' to the field 'answer_type' for each object.
For even integer answers, include 'half_answer' equal to answer ÷ 2.
If the response to a question is a string, add a 'first_char' field containing its first character.

Beyond the question-id fields, add a 'global_metadata' object with summary information:
Include 'num_questions_asked' to record the total number of questions presented.
• questions_with_integer_answers: ids of questions with integer replies.

Also include 'combined_results' consisting of:
  • integer_info (id → integer answer)
  • sum_of_answers (sum of those integers)

Now provide the result JSON using the described format.
