• I have an algorithm that performs some operation on a data structure using the public interfa

Answer 1

This method won't allow sharing data with the private methods unless you explicitly pass the data by method parameters.

module Thing
  extend self

  def pub
    puts priv(123)
  end

  private
  
  def priv(value)
    puts "Private method with value #{value}"
  end
end

Thing.pub
# "Private method with value 123"

Thing.priv
# NoMethodError (private method `priv' called for Thing:Module)
