So today I struggled to solve 1527B2 - Palindrome Game (hard version) officially today. I ended up getting wa tc 2, which seems pretty common at first. However, after the contest finished, I noticed that the ONLY reason why my solution wasn't correct was because I said "TIE" instead of "DRAW"

116825145 (The WA officially) 116845616 (AC after the contest)

I don't understand why problem writers can't spend time to include complete samples? I've written a few official CF rounds myself, and this is definitely not OK. Samples should always include all possible types of output. You can't argue the case that not including a "DRAW" case in samples will give away the problem either, because it clearly doesn't (001 is a trivial "DRAW" case).

Please do better next time. I'm super disappointed that none of the problem writers, the coordinator, or even any of the testers pointed this out. We look forward to these contests every time they happen, and it really sucks when your performance is ruined by a silly thing like this.
