A loaded question is something like 'Have you stopped swearing?' in which both yes and no answers mean that I have swore, meaning it is impossible to answer the question if I haven't swore.

However, the constructed language Lojban has a word na'i, which means there is something wrong with what you just said.

Your input should be a list of newline-seperated strings containing the following tokens:

  1. start followed by any integer (e.g. -1, 0, 1)
  2. stop + integer
  3. haveYouStopped + integer

You can assume that each stop n is followed by the corresponding start n.

Then for each haveYouStopped n in the code:

  • Print Yes, I have. + a newline if the last stop n occurs before the last start n
  • Print No, I have not. + a newline if the last stop n occures after the last start n, or at least one start n but no stop n is found in the previous line
  • Print .i na'i + a newline if no start n occurs in the previous lines.

The last newline is optional.

Examples:

start 1
stop 1
haveYouStopped 1

Output: Yes, I have.

start 1
haveYouStopped 1

Output: No, I haven't.

haveYouStopped 1

Output: .i na'i

All code is counted in UTF-8 bytes. Codepoints outside the UTF-8 range are not allowed. Use any language, shortest code wins. Also, no external sources are allowed.

    \$\begingroup\$ Please add more testcases, for example, more than one queries, start after stop, multiple start without stop (is it allowed?), stop without start (is it allowed?), n other than 1, testcases with multiple different n... \$\endgroup\$

    \$\begingroup\$ In your rules you say the output is No, I have not., but in your test case the output is No, I haven't.. So should it be have not, or haven't, or can we choose either? \$\endgroup\$ Nov 21, 2023 at 9:56

                            # (after which it is output implicitly with additional trailing newline)

See this 05AB1E tip of mine (section How to use the dictionary?) to understand why “Yes, I€¡.“ is "Yes, I have." and “No, I€¡€–.“ is "No, I have not.".

L$ms`d( \S+)$(?<=([pt])\1$.+?)?
$2.i na'i
p.+
YesI.
t.+
NoIn't.
I

Try it online! Link includes test cases. Explanation:

L$ms`d( \S+)$(?<=([pt])\1$.+?)?
$2.i na'i

For each haveYouStopped line, look for a previous start or stop line with that signed integer, and if so prefix the output with the final t or p, otherwise just output .i na'i.

p.*
YesI.
t.*
NoIn't.
I
, I have

If a start or stop was found then decode it to the desired output string.

Edit: Saved 17 bytes and corrected the Yes/No order thanks to @tsh.

Since this question counts in UTF-8, I didn't post a Charcoal answer, but had it been allowed it would have been 59 SBCS bytes:

Attempt This Online! Link is to verbose version of code. Takes input as a list of newline-terminated strings. Explanation:

≔⦃⦄θ

Start with all questions being impossible.

WS

Loop through the input strings.

¿№ιs

Does this string resolve a question?

§≔θΣι⪫⪪⎇№ιp¦Yes,.¦No,n't.¦,¦, I have

If so then save the appropriate answer.

⟦∨§θΣι.i na'i

Otherwise, output the saved answer, or the impossible answer if one wasn't saved.

(Assumes that you are referring to taking input as a newline-delimited string)

def decode(text):
    data = {}
    for line in text.strip().split("\n"):
        command, value = line.split()
        if "s" in command:
            data[value] = "Yes, I have." if "p" in command else "No, I haven't."
