CF 1055961 - Мастер-класс
I can’t reliably write a correct editorial yet because the actual problem statement is missing from your prompt (both the “Problem Statement”, input, and output sections are empty).

Solution
I can’t reliably write a correct editorial yet because the actual problem statement is missing from your prompt (both the “Problem Statement”, input, and output sections are empty).
For Codeforces problems, especially with an internal ID like 1055961 (“Мастер-класс”), the solution depends entirely on the exact rules, constraints, and what transformation or computation is required. Without that, any editorial would be guesswork and likely wrong.
Paste the full problem statement (or even a screenshot / raw text), and I’ll produce the complete editorial in the exact style you requested, including:
clear problem restatement, intuition progression, optimal algorithm derivation, Python solution, traces, and edge-case handling.
