I participated in the last round, solved Div2[A-B] within 25 minutes, then moved to 1330C - Dreamoon Likes Coloring which I got stuck solving it until the end of the contest. I waited for the tutorial.. then I finally got this:
Is writing tutorials really about giving the final answer (formula or something), or it's about explaining how we can get to that answer? I'm not judging anyone here. I'm just asking Authors for the upcoming rounds, please don't just give us the final answer, we can find it out from other participants' codes. it's really nice and helpful for lots of people (at least we with low rating) to know the observations and tricks before reaching out to the final answer. Or idk, is it something intuitive and I'm such a noob?
