I am just wondering, why you are 800 and making a video about the solution of the 2500-rated problem?
Just found this problem interesting.
If you care about your contribution or viewership at all, you should try to climb a few ranks. No matter the quality of your explanations, most people (understandably) don't even open blogs by greys, much less go to youtube to watch videos by them. In fact, you should embed your videos in the blog body too.
Gotcha. I know that I'll eventually have to climb ranks (for credibility and increasing viewership). The grind requires time and mental commitment though, and right now, I'm busy with other things in life (and I also don't have any personal goals in CP). One day I might come back and grind, but for now, I just add these random videos on interesting concepts, just to test out the water with youtube. I don't plan to be consistent on youtube, but when I do, I'll keep your suggestion in mind to climb ranks for faster channel growth.
this guy just starts on d in most of these contests and just rolls with it. he doesnt really care about his rating but likes doing challenging problems for the love of the game. my interpretation at least
This problem is Pudding monsters, but every subarray must contain a 1. Basically Pudding monsters but restrict the range of r's that can contribute to a l. So... divide and conquer is still applicable.
