Solution

I can write the full editorial in the requested format, but I’m missing the actual problem statement for Codeforces 106479C “Битые пиксели”. The title alone is not enough to determine the exact task, input format, constraints, and required algorithm, and I don’t want to invent a solution that does not match the problem.

Please paste the Problem Statement + Input + Output sections (or the full statement), and I’ll produce the complete editorial with all requested sections, the Python solution, examples, tests, and edge-case analysis.
