Expanded version of the Sudoku solver intro'd in Chapter 1 of Flanagan & Matz's "The Ruby Programming Language" -- solves 9 x 9, 16 x 16 and 25 x 25 puzzles (using an array rather than a string). Enter periods for empty cells, commas between cells, and use numbers (1..9, 1..16 and 1..25) for known values. Will automatically detect size of puzzle…
module Sudoku
class Puzzle
def initialize(lines)
if (lines.respond_to? :join)
s = lines.join(",")
else
s = lines.dup
end
