I came across this question in FB. I tried to solve but unable to get the answer for it. Feeling so demotivated. This is the question:
I need to turn the whole board WHITE.
Rules of the game:
1.When you select a square, the color of that square switches (from Black to White or vice-versa).
2.In the same move, the colors of the squares at the TOP, LEFT, RIGHT, BOTTOM of the selected square, if available on the board, switch (from Black to White or vice-versa) as well. Which squares should I select to win the game.
