for 7019
a = 1020
b = 5999
so that a + b = 7019
and digitsum for a = 3, b = 32 therefore result is 35.

My advice would be to look at the test cases and think hard about how to make them pass.

I didn't understand how to even start solving this question,
please i would like to know what would i need to learn to solve this type of questions
I know OOP but don't know how to solve this question

It could be like this:

a = 6999
b = 20

DigitSum(a) = 33
DigitSum(b) = 2

The sum of 33 and 2 is 35

I don't understand this question, there is just one exsample.
can someone write how the code should work for the number 7019:
how did the got to 35? and why?

Change Python version to 3.6. Read SO Martijn Pieters's post

So i wrote it again, i hope this is what you meant,
I have no idea how to mark it as a spoiler.

I got the same problem, my code works fine.

Happened to me too , my guess is that they want you to solve it for large n.
useally if you have nested loops in your code you will have this problem or this note.

which mean this is not the best way to solve it. On**2 Time

It could be you're using global vars, but I can't tell for sure without seeing your code. If you post it, use proper markdown and mark your post as having spoiler content.
