Loading collection data...
Collections are a way for you to organize kata so that you can create your own training routines. Every collection you create is public and automatically sharable with other warriors. After you have added a few kata to a collection you and others can train on the kata contained within the collection.

I was stuck on this exact test case with the same results.
If anyone else reads this and thinks "this guy is right - there's an issue," just go back and read the instructions carefully! There's a small detail you probably overlooked.
Can anyone shed some light on differences between big-integer handling in Python 2 vs Python 3?
I initially kept getting an error with my code running in Python 3 for one of the large-number test cases, but my output was only a few numbers away from the expected output. This seemed suspicious, so I changed to Python 2, and my code passed!
I've tried googling, and I've found some documentation explaining that 'long' is now 'int', but I don't think this explains my problem...
Any insight?
