There are three spirits, A, B, and C, how to make a judgment

This is an old logical question.

It's not a programming problem.

The questions are as follows:

1. Are you a spirit who tells the truth?

Note that at least 2 sprites will have the same answer to this question, because:

a Truth-tellers will certainly be yes.

b A liar is a liar because he is not telling the truth, but he cannot be not, so he is.

OK, if there is a 2+1 one, then the elf who is different from others must be the elf who randomly chooses the answer.

At the same time, the answer of more than 2 is the meaning of "right".

We continue to ask.

Are you a genie who randomly decides when to tell the truth?

a) The truth must be wrong.

b) Lies are affirmatively true.

At this point, the three elves and the others all know the answer.

If there are 3 identical answers, then the answer must be Yes

Are you a genie who randomly decides when to tell the truth?

a) Telling the truth is sure to be wrong

b) Lies are affirmatively true.

So, the answer is definitely a 2+1 result, and there can't be three identical results, because you already know what the answer is [true], then.

If 2 are right + 1 is wrong, then the wrong one must be the [Tell the Truth] elf.

Then choose any one and ask the elf who tells the truth if this is an elf who tells lies.

If so, then that one must be the one who told the lie, and the remaining one must be the one who randomly selected the answer.

If no, then that must be the one with the [random answer], and the remaining one is "lying".

If 2 are wrong + 1 is right, then the right one must be the [lying] elf.

Then choose one at random and ask the one who tells the lie if this is an elf who tells the truth.

If so, then that one must be the one that randomly chooses the answer, and the remaining one must be the one that tells the truth.

If no, then that must be the one who tells the truth, and the rest is the one that chooses the answer at random.

You can have as many as you want, but there are only 4 that can be shown.

Hello, the three gray elves are: Tias, Reinado, and Axia.

How hard is it? I indicated that I had the urge to put your question as a question.
