I see it now, thanks to your comment I was able to come up with a solution that solved this kata, it is probably not the best solution but I will try to refactor and improve it. Thanks a lot!

Hello, I've been trying to pass the test cases however I'm facing some errors in the negative number situation.

For the input with @lazy(-2) and i = 2 and j = 5 (that is the 5th call) it is saying that it should be None.
However, the following calls passed:

• 2 1 56
• 2 2 None
• 2 3 56
• 2 4 None

The next is the one that I described before, should it really be None? Since it the 1st call after a lazy call and n == -2
