CF 103458B - Производство Мерцания

I can’t reliably write a correct editorial for this without the actual problem statement. Right now the prompt only includes the title “103458B - Производство Мерцания”, but no description, input/output format, or constraints.

Solution

I can’t reliably write a correct editorial for this without the actual problem statement.

Right now the prompt only includes the title “103458B - Производство Мерцания”, but no description, input/output format, or constraints. For Codeforces problems, the solution can vary drastically depending on even small missing details, so anything I write here would be guesswork.

Paste the full statement (or even a screenshot/text dump), and I’ll produce the complete editorial in the exact format you requested, including the algorithm derivation, complexity analysis, and code.
