Dear friends,↵
↵
Today I tried an experimental format: separate videos. So, today I participated in [contest:1868] and recorded a screencast, but, unlike the previous times, I did not immediately record the editorials. Instead several videos are dedicated to them. So, here are the links:↵

* https://youtu.be/uuyVZcExbEI — screencast of [contest:1868];↵
* https://youtu.be/OFKF3oGhvmE — editorial (and upsolving!) of [problem:1869A];↵
* https://youtu.be/JoUOqDvKHuo — editorial (and upsolving!) of [problem:1869B];↵
* https://youtu.be/iS3eusWsx3E — editorial of [problem:1869C] (if you're interested in the coding part, you can find it here: https://youtu.be/uuyVZcExbEI?t=938);↵
* https://youtu.be/1Vu2RSQg0D0 — editorial of [problem:1869D1] and [problem:1869D2] (if you're interested in the coding part, you can find it here: https://youtu.be/uuyVZcExbEI?t=2688);↵
* https://youtu.be/Zn2OkKlgaG0 — editorial of [problem:1869E] (if you're interested in the coding part, you can find it here: https://youtu.be/uuyVZcExbEI?t=5204);↵
* sorry, no editorial of [problem:1869F] because I'm really tired. But with this format it is definitely possible that I'll post an editorial with upsolving later; for now you can read the [editorial](https://mirror.codeforces.com/blog/entry/116642) or watch https://youtu.be/uuyVZcExbEI?t=6640.
