I enjoyed the recent division 3 contest! However, test case 7 was illegal. In the constraints of the problem, x and y had to have a positive absolute value. However, test case 7 had many queries where x was 0, violating the constraints.

The second query caused my solution and many others to fail :( Could someone take a look into this?

I just looked at it .Luckily, i already took such cases into account but this is indeed carelessness on writer's part.

I think it should be retest, isn't it?

    Yeah retesting would be nice, but if a lot of contestants were affected it might result in an unrate due to the wasted amount of time debugging because of this "error"
