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_HDTYNt):
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: "is"

Question 1 (Question id: q_7MifI0Z):
Calculate ( 4 + -2 + 1 ).

Question 2 (Question id: q_U4BXgeu):
How many times does the letter "e" appear in the text: "electronic works in"? Respond with an integer.

Question 3 (Question id: q_PbJp):
Your task is to count how many legs there are in total when given a list of animals.

Now, how many legs are there in total if you have 1 ant, 3 dogs, 4 snakes, 2 cats?
 Respond with an integer.

Question 4 (Question id: q_CkGiZA):
Determine the value of w that satisfies: 13 - 17*w = -259 Respond with an integer.



Produce a JSON object whose top-level keys are the question ids.

For every question id, supply an object whose 'answer' field stores the solution.
Include an 'answer_type' field (value 'string' or 'integer') for every answer object.
For even integer answers, include 'half_answer' equal to answer ÷ 2.

Now provide the result JSON using the described format.
