This solution fails sometimes, and I have no idea why (it's just a "smart" brute force code). I've tried to reproduce the error several times on my pc, but I wasn't able to. And I've even tried to use python's long to no avail . Probably I am underfitting at some cases, but it works sometimes. :)

A problem must detail what needs to be done in its description. There is not only one way to do what's requested. You should probably add more test cases too, at least 5, to avoid lookup table solutions.
