Solution

The problem statement is missing from your prompt, so I can’t reconstruct the task or derive a correct algorithm for Codeforces 103136B - PSU.

To write a proper editorial in the style you requested, I need at least one of the following:

  1. Full problem statement (preferred), or
  2. Input/output description plus constraints, or
  3. A link or pasted text of the problem

Once you provide that, I’ll produce the complete end-to-end editorial with the structure you specified, including algorithm derivation, proof sketch, Python solution, worked traces, and edge cases.
