# n queens Algorithm

The eight queens puzzle is an example of the more general N queens problem of put N non-attacking queens on an n×n chessboard, for which solutions exist for all natural numbers N with the exception of N = 2 and N = 3.The eight queens puzzle is the problem of put eight chess queens on an 8×8 chessboard so that no two queens threaten each other; thus, a solution necessitates that no two queens share the same row, column, or diagonal. Chess composer Max Bezzel published the eight queens puzzle in 1848.Nauck also extended the puzzle to the N queens problem, with N queens on a chessboard of n×n squares. In 1874, S.
