Solution

I don’t have the actual problem statement for Codeforces 106290F (二维码生成器), only the title. Without the input/output specification and constraints, any attempt to write a full editorial would be guesswork and would very likely invent details that are not part of the problem.

If you paste the full statement (or even just the input format, output format, and constraints), I can produce the complete editorial in the exact style you requested, including the algorithm walkthrough, proof sketch, code, and test cases.

Send the statement and I’ll continue from there.
