# Given a string, replace every instance of sad to happy
#
# add_more_ruby("The clowns were sad.")         # => "The clowns were happy."
# add_more_ruby("The sad dad said sad stuff.")  # => "The happy dad said happy stuff."
# add_more_ruby("Sad times are ahead!")         # => "Happy times are ahead!"

def add_more_ruby(string)
  string.gsub('sad', 'happy').gsub('Sad', 'Happy')
end

#  I got this version to work also, the method above is alot cleaner though

# def add_more_ruby(string)
#   string.downcase!
#   string.gsub'sad', 'happy'
#   string.capitalize!
# end
