Problem 44364. Is this a valid Tic Tac Toe State?
Sorry for my english... but i can not understand why the test 6 has y_correct=0. I think that my problem is in understanding the problem description.
In test 6, player 2 (-1) wins but player 1 (1) continues to play.
I would miss illegal x=[1 -1 -1;0 1 -1;0 0 1].
It's difficult to say something about x=[1 -1 -1;0 1 -1;1 0 1].
Did X win after missing a win or did X continue to play after a win ?
Technically it's a legal state no ?
@Jean-Marie Sainthillier: If we'd number the nine cells of the grid as [1,4,7; 2,5,8; 3,6,9], then a series of moves that would lead to x = [1,-1,-1; 0,1,-1; 1,0,1] without "insensible" moves for X (the commencing party) would be: X:5, O:7, X:3, O:8, X:9, O:4, X:1 ; in that case, X did not miss a win nor continue to play after a win.
So it is controversial situation. I mean it is pretty legal situation
