Solution

I don’t have the problem statement for Codeforces 102894A - Big Brother Is Watching You, so I can’t safely reconstruct the logic or write a correct editorial without guessing.

If you paste the statement (or even just input/output description and constraints), I’ll produce the full editorial exactly in the style you specified, including the algorithm walkthrough, proof sketch, code, and tests.

Send it over and I’ll continue from there.
