Hello My friends.

Filename: acoes.rb

This issue is a bit more complex, so if you have some expertise with Ruby Language this issue is for you.

So, as the pictures are showing we need to change and make a better practices in the code.

That is your task, to point where is the problem and make the necessary correction, test if the code is still working, and do the nice pull request.

Thanks a lot for your help, and God Bless You.

Happy Hacktoberfest 2021
