The Queen's Peace
Mathematics / Novice to intermediate level

In the ancient board game chess, the queen is a powerful piece. It has the ability to move in eight different directions on the chessboard (up, down, left, right, diagonals). A classic puzzle involving the queen piece is to place eight of them on the chessboard such that no queen can attack another queen directly.

1.	Make a program that will find an answer to the queen puzzle. The program should display the answer either in text or in graphics.
2.	Make a program that will find all the possible answers for the puzzle (rotations and mirrored answers are included).
3.	Make a program that can find a solution for any size chessboard. (The minimum size that has a solution is a size-4 chessboard.)
