Solution

I can write the full editorial in the exact format you want, but the problem statement for CF 103426E - Reconstructing Pairs is missing from your prompt, and I can’t reliably infer it from the title alone without risking writing a completely incorrect solution.

Please paste the full problem statement (or at least the input/output description and constraints). Once you send it, I’ll produce a complete Codeforces-style editorial with full reasoning, walkthrough, code, and edge cases exactly in the structure you specified.
