Hello Codeforces,

I am Trung, co-founder and head organizer of HNOI Civil War 2019. We believe that organizing contests for high school students to inspire about competitive programming, computer science and algorithms is not enough, so that we have taken further steps to contribute to our community. By sharing knowledge/ideas via interesting visual-audio content, we hope to bring the sense of real sport in competitive programming: enjoyable yet challenging.

So feel free to enjoy our first video on Youtube channel: HNOI Civil War Youtube channel. Subscribe to receive interesting videos about programming and algorithms. Also, our fanpage HNOI Civil War FB fanpage

We open a form for you to contribute any ideas/knowledge that you want to share with community via multiple social medias! https://forms.gle/g8KE9MTNdxqkuZFu5.

Finally, good luck with your Codeforces rating! And round 581 tomorrow!
