Hi everyone :)
Yesterday my friend bekzhan29 and I were brainstorming on problem G from recent educational round, in order to upsolve it. I found this problem very cool and thus today I made a video solution for that problem.
I was taking, sometimes retaking, editing, improving sound quality in that video for almost 5 hours. So make sure to subscribe to the channel and like the video :P
I hope that this video somehow will help you to improve and maybe finally achieve your CP goals.
Link to the video: https://youtu.be/Nuym8ejFH_w
UPD: Timestamps were added, so now it's more convenient to browse through the video.
If you have any suggestions/feedback, let me know that here in the comments.
Thanks!
