I interpreted the puzzle to refer to words, hence

"ofouro"

When someone solves it I'll comment to congratulate that person and let them know they got it right.

Rest assured that there is only one correct answer and that everyone has thus far missed something which would lead them to it.

The smartest answer by far but something is still being missed.

But it is impossible know the characters previously the word though.
Púrpura comes firstly and then the characters

edit, I see this has been provided by Jamalrob but rejected by the poster... well I was never any good at logical puzzles.

Púrpura comes firstly and then the characters — javi2541997

Where does Púrpura come from?

Púrpura — Michael

What is the third character (number, letter, or symbol) you will type to solve this?

I was thinking about Púrpura because it was the first word that came to my mind

Another chance @DavidJohnson
I guess you are just asking for the headings

Why would that be relevant to the puzzle? It doesn't ask you to think of a word.

It is relevant because he is asking for a character in the first question. Where I get the character then? This is why I thought about an adjective. Trying to be original

He is saying that there is a single answer, let's say "xxx".

The first character is an answer to the question "What is the third character (number, letter, or symbol) you will type to solve this?"

The second character is an answer to the question "How many different characters will you type to solve this?" (although this could be more than one character)

The third character is an answer to the question "What is the first character you will type to solve this?"

@DavidJohnson

You need to clarify what you mean by different characters. Is the number 22 two different characters or 1 repeated character?

I think the OP has to clarify what is the extension in our "answers"
You put three digits (xxx) in your example, but I thought we were free to think whatever. That's why I typed "Púrpura"

I've refused to solve it, so I've solved it, just like everyone else who hasn't participated.

I've typed no characters to solve this, there are therefore zero characters I've type in response to it, and there wasn't a first character in my non-response.

To those who say my refusal to respond is a response, I say I'm not responding, but I'm just talking about stuff that I'm thinking about and not trying to solve this puzzle.

Mine is a good response, but not the response anyone was looking for, so there's that problem of course.

"Different" means distinct here so if the first and last characters were "3" then the answer to the second question would be "2" (the 3s are the same and the 2 is because it's distinct from the 3s).

(1,1,1) v (a,2,a) v (a,3,b)

1 & 3 are Arabic numerals!

I is a Roman numeral!

There, 3 distinct characters. Eureka!

None of the characters are different from one another, so there are 0 "different" characters.

The first is the third character and the third is the first character. Thus any x2x is solution with x<>2.

Or the special solution 111.

Except if you mean different characters as the letters in general and numbers. Then

The first and third characters are the blank character.

"Hamlet" is a string not a character.

Man. Wtf? I felt awkward reading this. It was a damn strange post.

Hamlet is a character in a famous play.
