Here is part-1's policy. Almost the same, just a slight difference on the valid? method:

class OldPasswordPolicy
  def self.from_line(line)
    length, char, password = line.split(' ')
    min, max = length.split('-').map(&:to_i)
    char = char.delete(':')

    OldPasswordPolicy.new(min: min, max: max, char: char, password: password)
  end

  def initialize(min:, max:, char:, password:)
    self.range = min..max
    self.char = char
    self.password = password
  end

  def valid?
    actual = password.count(char)
    range.include?(actual)
  end

  private

  attr_accessor :range, :char, :password
end
