Dynamic Programming - AtCoder educational dp contest

I will compete in the Educational DP Contest on AtCoder - atcoder.jp/contests/dp. I will approach problems from scratch, explain my thought process and implement everything. It's a perfect opportunity for you to learn more about dynamic programming concepts. The stream will be in English. The expected duration is 5 hours.

I'm going to stream on Twitch at the same time: www.twitch.tv/errichto.

Please ask questions in live chat.
I will be happy to answer them.
If you miss the stream, the video will be available later anyway.

What is Competitive Programming? en.wikipedia.org/wiki/Competitive_programming

I'm known as Errichto. I compete in and organize programming competitions. I'm a finalist of ACM-ICPC, Topcoder Open, Facebook Hacker Cup and Google Code Jam. I got a second place in Google Code Jam 2018. Watch me if you want to practice Competitive Programming, algorithms or you want to learn for a coding interview. I share my thought process, explain everything, and mention similar problems that I know or techniques/algorithms that could be used too. Learn from me and grow your rating on Codeforces!
