Solution

I can write the full editorial, but I’m missing the actual problem statement for Codeforces 103107H - Hack DSU!.

Right now I don’t know:

what operations DSU supports in this problem, what “hack” means in context, or what the input/output is supposed to represent. Any attempt to infer it would risk producing a completely incorrect editorial.

Please paste the full statement (or even a screenshot/text dump), and I’ll turn it into a complete Codeforces-style editorial in the format you specified.
