It seems like lisp is a lot like nuclear power: everyone discounts it before they even know what it is, or what it's like, because they don't understand it

statistically nuclear power is safe power

safer than fossil fuels, hydro, solar, wind

And then when Lisp explodes it's a lot like nuclear bombs as well

except there's parens everywhere instead of waste

If you don't use macros, lisp is basically Python with a funky syntax.

@EriktheGolfer Regarding your sandbox post

Erik the Golfer

2:39 PM

Yeah, I read the comments.

Fatalize

Take
XXX
_X_
__X

If you only look at X then this board is valid

because it could be that the previous board is
_XX
_X_
__X

And in general it will be true for any board that I can think of if you ignore the other player

Erik the Golfer

I do not mean only look at the X, I think you haven't understood the challenge well.

Fatalize

So it makes no sense to me to check the validity for one player

Show me a situation which is valid for X and invalid for O

Erik the Golfer

The one player thing is who starts the game, not who to only check. This is because the starter must have 5 of their marks in the board, while the opponent must have 4. Not something more than that.

Fatalize

I still don't get it

You never say in your post who is supposed to start

Erik the Golfer

2:43 PM

Haven't I included the word "starter"?

Fatalize

Just show me an example that is valid for X and invalid for O and explain to me

this will be simpler

Erik the Golfer

Basically, any example valid for X will be invalid for O, since X will have 5 marks and O will have 4 marks. For X, it is valid, because they have 5 marks, and in positions that could be played in. For O, it is invalid, because after the fourth X, it will be O's turn, but instead a fifth X is on the board.

Example:

X__ XO_ XOX XOX XOX XOX XOX XOX XOX
___ ___ ___ __O __O __O __O O_O OXO
___ ___ ___ ___ __X _OX XOX XOX XOX

Geobits

What would the output be if it's valid for one player starting and not the other? I assumed the challenge was "is this board possible" at all, and only a single truthy/falsey value.

Fatalize

I don't see how your example is invalid for O

Erik the Golfer

It's when O is the starting player that it is invalid.

Fatalize

2:49 PM

"Given a tic-tac-toe board in any format, determine if it is valid or not"

If we are not given who starts it makes no sense

Geobits

It makes sense if the question is "is it valid for any (not all) starting player?"

"Who starts" is not input, it's hardcoding, which I am strong against. That's why I have included the bonus, which will probably become a necessity.
