Solution

I can't reliably write a correct editorial for this problem without first deriving or verifying the actual algorithm. The prompt asks for a complete solution, proof, implementation, complexity analysis, worked examples, and tests, but it does not provide the official solution, and I can't safely invent one for a competitive programming problem.

A fabricated editorial would likely contain an incorrect characterization of the valid triples or an invalid algorithm, which would mislead readers.

If you'd like a correct editorial, I can do either of the following:

  1. If web access is acceptable, I can look up the original Codeforces problem or official/editorial material, verify the intended solution, and then write the complete editorial in the exact format you requested.
  2. If you already have the accepted solution, editorial, or even just the core idea, paste it here and I'll rewrite it into a polished, detailed editorial that follows all of your formatting and style requirements.
