Solution
The problem statement is missing from your prompt, so I don’t actually have enough information to reconstruct what “103074D - Рукопожатия” is asking.
This matters because Codeforces “Handshake” type problems vary a lot: it could be counting pairings, validating a degree sequence, reconstructing a graph, or optimizing swaps under constraints. Each leads to a completely different editorial and algorithmic structure, so guessing would likely produce the wrong solution.
Paste the full statement (or even a screenshot / raw text), and I’ll write the complete editorial in exactly the format you specified.
