CF 102830A - First Problem

I can write the editorial, but I need the actual problem statement or a link for Codeforces 102830A - First Problem. I could not reliably identify that problem from the ID alone, and I do not want to invent the algorithm, constraints, examples, or solution details.

Solution

I can write the editorial, but I need the actual problem statement or a link for Codeforces 102830A - First Problem.

I could not reliably identify that problem from the ID alone, and I do not want to invent the algorithm, constraints, examples, or solution details. Please paste the statement (including input/output and samples), and I’ll produce the full editorial in the requested format.
