Solution

I can’t write a correct editorial yet because the actual problem statement for Codeforces 103643I - Late Midnight Assignment is missing from your prompt.

Right now only the template sections are present, so there’s no information about what the input describes, what transformation or computation is required, or what constraints shape the solution. Any attempt to proceed would be guesswork, which would defeat the purpose of a precise Codeforces-style editorial.

Paste the full problem statement (or even just the Input/Output + constraints section), and I’ll produce the complete editorial in the exact format you specified, including the reasoning, optimal approach, walkthrough, code, and edge case analysis.
