I was doing some problems of [user:SlavicG,2020-11-25] and [user:ssense,2020-11-25]'s Unofficial Div 4 round. [This problem](https://codeforces.me/gym/102873/problem/B) was causing me with some weird Idleness Limit Exceeded. [submission:99582268]. After being Sherlock Holmes for a few minutes, I fixed the problem and [submission:99582838] is AC. The weird thing is the $dbg$functionmacro. 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?
