Originally, every square of a \( 8\times8\) chessboard contains a rook. A rook attacks another rook if they are on the same row or column and there are no other rooks between them. You may remove a rook (one at a time) if it currently attacks an odd number of rooks.

Find the maximal number of rooks that can be removed.
