Solution
The problem statement is not included in your prompt (the sections for input/output are empty). Without the actual description of Codeforces 105520B - “Телефон”, it is impossible to produce a correct editorial, because the entire solution structure depends on what is being computed, what the input represents, and what constraints apply.
If you paste the full problem statement (or even just the core description and constraints), I can immediately write the complete editorial in the exact format you requested.
Right now, any attempt to proceed would require guessing the problem, which would make the editorial incorrect and not usable for learning or contest preparation.
