Solution

I don’t have the actual statement for Codeforces 103729A “Nucleic Acid Test” in the prompt you provided, so I can’t safely reconstruct the intended problem or derive a correct solution without guessing.

If you paste the full problem statement (or even just input/output format and constraints), I’ll produce the complete editorial in the exact style you requested, including the full algorithm walkthrough, proofs, code, and tests.
