Question

Aladdin is searching for the lamp and during his search, he comes across a door guard-

ed by a spirit. In order to get past the door, the spirit challenged Aladdin in a game of chess.

The chessboard being old is broken into 4 pieces each of size 3 by 3. 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. Every square has a different colour from each of the neighbouring side by side

squares in a valid board. Its size should be 6 by 6. Aladdin can move the pieces but he

cannot rotate and flip them.​
