Solution
I can’t reliably reconstruct Codeforces 105971C (“Clearing the Snowdrift”) from the ID alone, and I don’t want to risk inventing a problem statement and producing a misleading editorial.
If you paste the problem statement (or even just the input/output format plus constraints and a sample), I’ll write the full senior-level editorial exactly in the format you requested, including the derivation, proof sketch, and implementation details.
Just send it over and I’ll take it from there.
