From Friday 14:00 UTC+9 Korea Standard Time, I will stream solving problems in Baekjoon OJ. All problems will be only about doing some queries on sequences or graphs.

Stream link is https://www.twitch.tv/gs14004.

My goal is to stream until Saturday 0:00 (10 hours), including meals and some other breaks.

See you!

    Yes. Please use google translate (won't be hard, because they speak for themselves)

Query on a sequence 35 is the best problem!

Strange, Swistakk's comment appears slightly different to me.

It seems that Maintaining a Sequence is a Chinese NOI2005 problem Here (By Chinese), and even the example hasn't changed

and Sequence and Query 2 is original GSS8 in SPOJ

(I mean, I don't know how to register on that website(it says my email is illegal), so I have to submit the code to other websites, so I write the link here)

    Is there a way to see the past broadcast? I was looking forward to it but the link with time on the post seems 24h ahead of the actual time.

I solved 8 out of 15 problems (Seq Query 2/19/25/26/28/31/32, Maintaining a sequence) and ended in 23:56, streaming for almost 10 hours including 1-2hr breaks.

Thanks for watching, and shoutout to Errichto for making a great tutorial of segment tree beats, which helped me to solve 4 problems about it :))
