CF 105709D - Sample Collecting

I’m missing the actual problem statement for Codeforces 105709D - Sample Collecting (your prompt shows an empty section). Without the statement, any “editorial” would be guesswork, and for this format that would very likely drift into explaining the wrong problem.

Solution

I’m missing the actual problem statement for Codeforces 105709D - Sample Collecting (your prompt shows an empty section).

Without the statement, any “editorial” would be guesswork, and for this format that would very likely drift into explaining the wrong problem.

If you paste the full statement (or even a screenshot / rough description), I’ll write the complete senior-level editorial in the exact style you requested, including algorithm walkthrough, proofs, code, and edge-case analysis.
