Solution

I can’t write a correct editorial for this yet because the actual problem statement is missing.

“Codeforces 102951B - Studying Algorithms” alone doesn’t contain enough information to reconstruct the task, constraints, or required technique, and guessing would very likely produce a completely wrong solution and misleading editorial.

If you paste the full statement (or even just input/output description and constraints), I can immediately turn it into a proper Codeforces-style editorial in the format you requested, including the derivation, proof sketch, code, and edge case discussion.
