What is Queens Problem?
The N Queens Problem is a puzzle of placing N Queens on a N * N Chessboard in such a way that no two queens can attack each other i.e., no two queens should be placed horizontally, vertically or diagonally. In other words, any queen should not be in the same row, column or diagonal of any other queen.
In other words, any queen should not be in the same row, column or diagonal of any other queen.
N represents the number of queens. So, when N = 1, it’s a trivial case. For N = 2 and N = 3, the solution is not possible.Therefore, we start with
Therefore, we start with N = 4. Normally, 4 Queen’s Problem and 8 Queen’s Problem are famous questions for its applicability.
