Solution

I don’t have the actual statement for Codeforces 106034B “QR-код” in your prompt, so I can’t responsibly write a correct editorial yet.

This problem ID looks like a localized/archived task, and without knowing what the grid/input rules are (what a “QR code” represents here, what transformations or queries are required, and what the output should compute), any solution would be guesswork and very likely wrong.

If you paste the full problem statement (or even just input/output + constraints + sample), I’ll immediately turn it into a complete Codeforces-style editorial in the format you specified, including the algorithm walkthrough, proof idea, implementation, and test suite.
