Apart from that, some squares are of the wrong colour with j-th square of the i -th row of k-th piece of the board has colour ak,i,j . The spirit wants Aladdin to change the colour of some squares in such a way that he recolours the minimum number of squares and the obtained pieces form a valid chessboard.

What is the minimum number of colours Aladdin should recolour to obtain a valid chessboard and get past the door?
