CLI
Added a CLI.
Nice feature!
Unless I'm missing something I think you accidentally added some temporary files from your editor (ending with ~)
Could you remove them and squash?
Oh!... I am still new to Ruby. Can you tell me where this method get_input_number is.
I will remove the temporary file and upload ASAP
Regarding the get_input_number, in the validate method you use the get_input_number method, but in the calculate method you seem to reimplement it?
Oops..I will correct it and upload. That has been a silly mistake...
No worries mate, just make a new commit and squash your branch and then force push it.
