CF 104708A1 - Build a Pair A1

I don’t have the actual problem statement for Codeforces 104708A1 - Build a Pair A1, so I can’t reliably reconstruct the task, constraints, or solution. Writing a correct editorial without that would be guesswork and would very likely be wrong.

Solution

I don’t have the actual problem statement for Codeforces 104708A1 - Build a Pair A1, so I can’t reliably reconstruct the task, constraints, or solution. Writing a correct editorial without that would be guesswork and would very likely be wrong.

If you paste the full statement (or even a screenshot / partial text), I’ll produce the complete editorial in the exact format you requested, including problem understanding, full derivation of the optimal solution, proof sketch, implementation details, examples, and tests.
