Solution
The problem statement for Codeforces 103428L - shake hands is missing in your prompt (it’s empty after “Problem Statement / Input / Output”). Without the actual rules of the problem, there’s no way to correctly reconstruct the intended model, constraints, or solution strategy.
For a Codeforces editorial, even small differences in wording can completely change the solution class (graph matching vs greedy vs combinatorics vs simulation), so guessing here would likely produce a wrong or misleading write-up.
Please paste the full problem statement (or at least the input/output description and constraints), and I’ll produce a complete, Codeforces-style editorial in the exact format you requested.
