Programming Project: N-Queens Prerequisites: Chapter 5 For this project you will create a class that solves a variation of the 8-Queens Problem, the N-Queens Problem. If you need a recap of the 8-Queens Problem watch this video. The N-Queens Problem is identical to the 8-Queens Problem except we vary the size of the board. So, we can find the placement of queens on a 4x4 board (the 4-Queens Problem) or a 9x9 board (the 9-Queens Problem), etc. Your solution to the N-Queens Problem will be implemented entirely in the class ChessBoard which will at minimum include:
