## rooks problemTo find the maximum number of chess rooks that can be placed on an n × n chessboard such that
no rook attacks another. Since each rook attacks all squares in the rank
and file upon which it rests, this number is n: the rooks may be
placed along the diagonal. The total number of ways of placing n
non-attacking rooks is n factorial (n!). ## Related category• GAMES AND PUZZLES | |||||
