Hi,

Test case works on my computer but not on the server. It tells me that I need to return -1 when I am returning 0, but in actual fact, I know I am dropping into the condition that returns -1 since I've attached print statements. Any ideas why?

Cool. That's what I thought as well. I always fall into the trap of striving for extremely efficient solutions; should have realised that this has a high lower bound. Thanks for the quick reply!

Azuaron, do you mind stating the time complexity of your solution? I have a vague idea, but I am not too sure.

Still has not been fixed.

Hi Alex, I still do not really get your explanation. How does the bitwise OR help preventing an infinite loop here?

Hi! Yes it is resolved! I don't see any button to resolve it on my end. I think it should be something you do. Am I wrong?

Will be great if there are more test cases.
