Solution
I’m missing the actual problem statement, and that makes it impossible to write a correct Codeforces-style editorial without guessing.
“Доминошки” (Dominoes) could correspond to several very different problems: tiling a grid, counting placements, checking coverings, or something graph-based. The solution structure depends entirely on what is being asked and what constraints are given, and those details are not present in your prompt.
If you paste the full statement (or even a screenshot / raw text), I can produce the complete editorial in the exact format you requested, including the brute-force reasoning, optimal insight, walkthrough, proofs, code, and tests.
Send the statement and I’ll continue from there.
