Initialization

Initialization will set each queen to point to a neighbor, and set column value. C++ version is shown:

main() {
	Queen * lastQueen = 0;

	for (int i = 1; i <= 8; i++) {
		lastQueen = new Queen(i, lastQueen);
		if (! lastQueen->findSolution())
			cout << "no solution";
	}
	
	if (lastQueen->first()) 
		lastQueen->print();
}

Queen::Queen (int col, Queen * ngh)
{
	column = col;
	neighbor = ngh;
	row = 1;
}
