N-Queens Problem Introduction

The N-Queens problem asks:

"How can N queens be placed on an NxN chessboard so that no two of them attack each other?"

To explore this problem, enter the desired board size below and click "Set Board Size". Then, click on squares on the board to place queens. You can also remove queens by clicking on squares that already have queens.

Your goal is to place the same number of queens as the board size you specified. Good luck!
