Solution
I cannot reliably write a correct editorial yet because the actual problem statement for “Codeforces 1055974 - Бирмингем” is not available in the provided prompt, and it is not directly accessible from standard Codeforces problem listings.
The structured editorial you requested depends entirely on knowing what is being asked (input format, constraints, and task), since every section from the algorithm design to edge cases is derived from the problem specification. Without that, any solution would be guesswork and would likely be incorrect or misleading.
If you paste the full statement (or even a screenshot or partial text), I can immediately produce a complete Codeforces-style editorial in the exact format you requested, including:
A clean restatement of the problem in my own words, a full constraint analysis, a derivation of the optimal algorithm, a rigorously explained walkthrough, Python implementation, and traced examples.
