CF 102942C - Team
I can’t write a correct editorial for Codeforces 102942C - Team without the actual problem statement. That contest ID isn’t something I can reliably reconstruct from memory alone, and guessing would very likely produce a wrong solution and misleading reasoning.

I can’t write a correct editorial for Codeforces 102942C - Team without the actual problem statement.
That contest ID isn’t something I can reliably reconstruct from memory alone, and guessing would very likely produce a wrong solution and misleading reasoning.
Paste the full statement (or even just the input/output description and constraints), and I’ll produce the complete editorial in the exact style you requested, including algorithm walkthrough, proof sketch, code, and tests.
