But what if it word has a digit?

n has 2 digits or n < 100. It is in the description:

you can stop when this number has at most 2 digits because you are supposed to know if a number of at most 2 digits is divisible by 7 or not.

The maker of the test need to specify what the final condition for divisable by 7 means....

You can go under Kata/Completed in your profile to see all completed katas. If you want the code, you can open an already completed kata and choose "Past Solutions" in the left side with Instructions and Output. Solutions/Completed on your profile also work.
