Solution

I cannot responsibly write a correct Codeforces-style editorial for 105691B - RecoveriT yet because the actual problem statement is not available in the context you provided, and it is not accessible from the retrieved sources.

Right now, anything I write about the task would be guesswork, and that would defeat the purpose of a technical editorial.

If you paste the full statement (or even just input/output description plus constraints and samples), I can immediately produce a full senior-level editorial in the exact format you requested, including:

  • clean problem modeling
  • optimal insight derivation from brute force
  • correctness proof via invariants
  • full Python solution
  • worked traces and edge case analysis

Send the statement and I’ll turn it into a complete Codeforces editorial.
