Hello,

I have been spinning my head around this test case for a while now.

Could you please provide the full test case grid?

I thought it was the overflow of the unsigned long long value, but this didn't work.

I thought it was the memory limit, but apparently this wasn't the case.

I tried to mimic the grid by using this form;

0 3 3 3 3 3 3 3 3

And then, my solution outputs the correct value of 3 in the missing cell. (Isn't it?)

Any hints will be appreciated!

Thank you!
