Question
A Queen on a chessboard can attack any piece in the same column, row or
diagonal. The N-Queens problem is to place n queens on an x n chessboard
such that no two queens threaten each other.
a) Implement a one-dimensional integer array of Queen positions for an 8x8
board where indices represent rows and the values represent columns.
For example, a "safe" solution would be (3,6,2, 7, 1, 4, 0,5}
b) Implement a print function to display the board (see output example)
c) Implement an isSafe function that:
1) Returns false if multiple queens share a column
2) Returns false if multiple queens share a diagonal
3) Returns true if all queens are safe
d) Program should display if the Queens are safe or not safe.
Example Output
Testing: 1 4 2 3 5 7 60
Queens are not safe!
