    In a chess game, you are given 8 queens (color doesn't matter)and you have to place them on the board such that no queen kills any other (or is under direct attack). solve the puzzle by placing the 8 queens according to the condition.

    This is a classic computer science '8 Queens Problem'.
    A solution requires that no two queens share the same row, column, or diagonal. There are in all 92 solutions to this problem. But if the solutions that differ only by rotations and reflections of the board are counted as one, the puzzle has only 12 unique (or fundamental) solutions.
