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.
Get started now by creating a new collection.
What is the point of this test: test.assert_equals(arr(), []) ??????
Gotcha, thanks!
why not just assign the lengths of "l" and "d" to variables. This calculates the lengths of "d" and "l" 4 times.
I know the lengths of them are quite small in this kata, but still this doesn't seem efficient.
Nailed it!
I think there are some issues with cases in attempt:
solve(100000000000,3)
elif a >= 2b: return solve(a-2b, b)
