I've implemented this problem two different ways and I have WA9 on both of them. I'm possibly interpreting the problem wrong, but I've read the problem over and over again and I cannot come up with an alternative interpretation. Can someone please shine some light?

Try to fix checker, please. It's possible, that some programs output more than m pairs but got AC.

could you test it again? i've no idea whats wrong

Could you please verify test #5 and my program's output on it? I'm checking everything inside my program and it does not get OLE, but still it gets WA#5.

My AC: 0.015 121KB
