Solution

I can’t write a correct editorial from just “H” and an empty statement.

Codeforces 105851H (“Link与矩阵除法”) clearly has missing problem content in your prompt, so there’s no way to reconstruct:

  • what the input actually represents (matrix operations, graph, strings, etc.)
  • what operation “division” refers to in this context
  • constraints, which determine the intended complexity class
  • even the required output format

If you paste the full problem statement (or even just input/output + constraints + samples), I’ll produce the full editorial in the exact style you requested, including:

a clean intuition story, optimal derivation, step-by-step algorithm, proof sketch, implementation, and edge case analysis.
