I can’t reliably write a correct Codeforces-style editorial without the actual problem statement.
Right now the only information available is the title “Генератор деревьев (Tree Generator)”, but there is no description of what is given in the input, what must be constructed or computed, or what constraints apply. Any attempt to “fill in” the missing problem would almost certainly invent the wrong task and produce a misleading solution.
If you paste the full statement (or even a screenshot / rough description), I’ll write a complete senior-level editorial in the exact format you requested: full reasoning, algorithm derivation, proof sketch, implementation details, edge cases, and tests.
Just send the statement and I’ll continue from there.
