CF 103075B - Рудольф и диагональный сканер

I can’t reliably write a correct Codeforces editorial here because the actual problem statement is missing. Right now, all I have is the title “Рудольф и диагональный сканер”, but no description of the grid, operations, or required output.

Solution

I can’t reliably write a correct Codeforces editorial here because the actual problem statement is missing.

Right now, all I have is the title “Рудольф и диагональный сканер”, but no description of the grid, operations, or required output. For problems like this, even small details (what “diagonal scanning” means, what is being counted, constraints) completely change the solution approach.

Paste the full statement (or even a screenshot/text dump), and I’ll produce the full editorial in exactly the format you specified, including the algorithm walkthrough, proof, implementation, tests, and edge-case analysis.
