I've been asked a lot about the fibonnacci sequence functions (iterative and recursive) during interviews.
Can I add the question here with the solution?

[RaviKarrii]

Yes Please. Anything that would help users prepare for interviews.

You may also add your GitHub ID if you like. may be say ( added by (User))

Great! Should I add in as a markdown file, as a python file or both?

[RaviKarrii]

You can create the program in a folder named "Supporting files" in python folder. and link it in markdown file
