Solution
The problem statement for “Codeforces 1055191 - Лифты (Elevators)” is not included in your prompt, so there isn’t enough information to reconstruct the task reliably.
Because the editorial depends entirely on the exact rules (how elevators behave, what the input encodes, and what is being optimized or computed), any attempt to proceed without the statement would be guesswork and would risk producing a completely incorrect solution write-up.
If you paste the full statement (or even just the input/output description plus constraints), I’ll write the complete editorial in the exact style you requested, including the derivation, optimal approach, walkthrough, code, and edge-case analysis.
