Codeforces Round 896 — screencast and editorial

Правка en3, от orz, 2023-09-16 18:52:55

Dear friends,

Today I tried an experimental format: separate videos. So, today I participated in Codeforces Round 896 (Div. 1) 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:

UPD: I recorded the upsolving of 1869F - Flower-like Pseudotree (see the link above). I guess my explanation were quite fine, but in one case I incorrectly calculated the preconditions, which resulted in a huge mess and pain. It is still quite educational stuff though: the first half of the video is just a normal editorial (but, alas, with a technical mistake which should't screw the flow of the problem though), and the second one can teach you how to seek for bugs in problems like this one (with a big number of cases).
