Solution

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

“Codeforces 104150A - Допрос подозреваемых” (Interrogation of suspects) isn’t enough to reconstruct the task, and guessing would almost certainly produce a wrong solution, wrong invariants, and a meaningless complexity discussion.

If you paste the full statement (input format, constraints, and output definition), I’ll produce the complete Codeforces-style editorial exactly in the structure you requested, including the algorithm walkthrough, proof idea, Python solution, worked traces, and edge-case analysis.
