Solution

I can write the full editorial in the exact structure you want, but I’m missing the only thing required to do it correctly: the actual problem statement.

“Codeforces 105971M - ZP” doesn’t give me enough information to reconstruct the task reliably, and guessing would lead to a fake editorial.

Please paste one of the following:

  • full problem statement, or
  • at least input/output format + constraints + what needs to be computed, or
  • a link plus key details if it’s from a private or mirror contest

Once you send that, I’ll produce the complete editorial in the format you specified (problem understanding, approaches, walkthrough, code, proofs, tests, edge cases, everything).
