Solution

I can write the full editorial in the exact format you want, but I need the actual problem statement content.

The link alone (921/problem/01) is not accessible from here, and without the statement I’d have to guess the rules, which would make the editorial unreliable at a 3200-rated level.

Please paste one of the following:

  1. Full problem statement text

or 2. A condensed version including input/output format and constraints

or 3. Key description of the “Labyrinth-7” rules (grid/graph/interactivity/etc.)

Once you provide that, I’ll produce the complete Codeforces-style editorial with:

clear intuition, optimal algorithm derivation, full walkthrough, proof sketch, code, and edge-case analysis exactly in your requested format.
