not an issue

Hi I am getting the same frustrating error that the 'server is timing out'. I have tried refactoring the code, any pointers as to how i can refactor? or what I need to be aiming for, shooting in the dark with this one.

Yep, they are indeed much larger and much more numerous.

I keep getting that today too ... looking at some of the other postings here, I get the idea it's a timeout due to the submit test cases being much larger numbers than the test test cases. Next step, more optimization. :-)

That goes outside my control; try to resubmit in a short while and it might work :)

You are attempting to solve the problem with a brute-force approach, which will never work as you will time out.

As you could have read in other comments below, you should find another approach.

Your parentheses are unbalanced.
