Solution
I can’t reliably write a correct Codeforces editorial from that prompt because the actual problem statement is missing.
“104770F - Segment Tree” alone is a Gym-style label and could correspond to many different tasks: range assignment, lazy propagation variants, segment tree beats, persistent tree queries, or something entirely unrelated. Each of those leads to a completely different solution structure and proof.
If you paste the full statement (or even just the input/output description and constraints), I’ll write the full editorial in the exact style you requested, including the derivation, correctness argument, and a clean implementation.
