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_k0sJ8):
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: "we"

Question 1 (Question id: q_zdhh):
How many times does the letter "f" appear in the text: "of single"? 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.
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.

Add a top-level 'global_metadata' field that records overall stats:
Include 'num_questions_asked' to record the total number of questions presented.
• num_questions_answered – number you actually answered.
• 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.
