this wont work with 0 thus the condition 1 2 3 should be only true

Why make description so confusing for 8kyu

what kind of sob voted this as a spoiler

Looking at this and realising assembly does not seem that bad.

Its more like 6kyu

Nice. But description is a bit confusing. ("66443875", 4) --> "44668753" means that it shoud be 4 dig in each chunk and not str divided into 4 chunks. Thus ['6644', '3875']
Sadly he did not mention it in any example to make out life easier of course.

This is so funny. Maybe she needs some glasses :D

Just try to opimize it. If the logic is correct the rest is easy. Try to cut it or use different methods and one loop only.

this should be at least 7kyu but not 8kyu

Mr.Obvious :D

I agree. Its not even 1 grade math how its possible to make such a mistake and make me rethink ten times to add up to those .10

you can skip false and true
