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_i9nQy3I):
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: "compete"

Question 1 (Question id: q_ku61g9t):
How many times does the letter "b" appear in the text: "library of"? Respond with an integer.



Output JSON where all question ids are keys, omitting q_i9nQy3I.

For every question id, supply an object whose 'answer' field stores the solution.
For even integers, nest 'half_answer' and 'double_answer' inside an additional 'additional_answer_info' field in the answer object.
If the response to a question is a string, add a 'first_char' field containing its first character.
If the question asks for the last character of a string, add an 'original_string' field containing the source string.

Now provide the result JSON using the described format.
