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_WCFV3AE):
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: "problems"

Question 1 (Question id: q_E3UnN8If):
How many times does the letter "f" appear in the text: "freely distributed in"? Respond with an integer.

Question 2 (Question id: q_L1UKphZ):
Determine the value of n that satisfies: 12 - 16*n = -100 Respond with an integer.

Question 3 (Question id: q_IHujv):
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: "it"

Question 4 (Question id: q_je901I):
Calculate ( ( 6 * 3 ) ).

Question 5 (Question id: q_lF5qZziw):
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: "economy"



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.
If the response to a question is an integer that is even, also add the field 'half_answer' to the object which contains the answer integer divided by two.
If the response to a question is a string, add a 'first_char' field containing its first character.

Add a top-level 'global_metadata' field that records overall stats:
'num_questions_asked' should equal the total questions that appeared.
• num_questions_answered: count of questions present in your JSON.

Now provide the result JSON using the described format.
