Question 6 (Question id: q_k3brjtY):
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: "full"



Return a JSON with each question id as a key.

Each key’s value must be an object holding an 'answer' field.
If the response to a question is an integer that is even, add the field 'additional_answer_info' containing 'half_answer' (answer ÷ 2) and 'double_answer' (answer × 2).
If the response to a question is a string, add a 'first_char' field containing its first character.
For last-character tasks, provide 'original_string' alongside the answer.

Now provide the result JSON using the described format.
