NOTE: This problem is NOT interactive
I was doing some problems of SlavicG and mesanu's Unofficial Div 4 round. This problem was causing me with some weird Idleness Limit Exceeded. 99582268. After being Sherlock Holmes for a few minutes, I fixed the problem and 99582838 is AC. The weird thing is the $$$dbg$$$ macro. After commenting all of the dbg's out, it got AC. I am wondering why is this. Shouldn't it be outputted to the standard error stream? Why am I getting this idleness limit exceeded?
