Staircase

  • mvanlamz + 1 comment

    Range and map is more ruby-esque:

    def staircase(n)

    (1..n).map{|x| "#{' ' * (n - x)}#{'#' * x}"}.join("\n") + "\n"

    end

    n = gets.to_i

    puts(staircase n)

      Alternatively you can also use Integer#upto

      def staircase(n)
  1.upto(n) { |i| puts ('#' * i).rjust(n) }
end

n = gets.to_i
