Codeforces Round #439 (Div. 2) Editorial

Правка en5, от Tommyr7, 2017-10-07 09:29:23

Hi, all!

This is not Tommyr7, but the impostor behind the round (guess who I am? :P). The statements are written by me. The characters in the round feature, again, the Monogatari anime series, and to be more specific, Nisemonogatari: Fake Tale. The statements involve stories with fake things and oddities, but as per tradition, contain no spoilers. Thank you, everyone, and hope you've all enjoyed the round!

On a side note, special kudos to the best impostors of the round (except me, lol)!

Any feedback on problems and tutorials are welcome -- we look forward to doing even better in the future!

Here are hints for all problems and detailed tutorials for most of them. Stay tuned, more are coming!
