N-Queen Problem

The "N-Queens Problem" is a classical problem of chess. Here N Queens are to be placed on an N * N chessboard in such a way that no queens attack each other. A Queen can attack other Queens if its placed on the same row, column or on its diagonals. We use Backtracking in the backend to solve this problem .

Usage

To Install this package. Use :

pip install nqueens
