Your output must be a JSON mapping every question id to its answer info.

Each key’s value must be an object holding an 'answer' field.
For even integer answers, include 'half_answer' equal to answer ÷ 2.
For string answers, include 'first_char' with the answer’s initial letter.

Now provide the result JSON using the described format.
