Hi everyone!↵
↵
I recently come across this interesting topic of **Round-Square Tree** in the solution for the recent AtCoder Beginner Contest. [This](https://atcoder.jp/contests/abc318/editorial/7090) is the link for the editorial which refers the concept.↵
↵
I find the idea interesting as it is simpler than the official solution which uses network flow. But I couldn't find much resources on the topic online. ↵
↵
So if anybody knows about the topic or have some resources then please add them in the comments. ↵
Also if you know some questions related to this topic, do attach them in the comments.↵
