I can't reliably write a complete editorial and accepted implementation for Codeforces 1425I from the statement alone. This is a 2800-rated data structure problem whose solution depends on a fairly specific exploitation of the height ≤ 10 ternary-tree structure.

Solution

I can't reliably write a complete editorial and accepted implementation for Codeforces 1425I from the statement alone.

This is a 2800-rated data structure problem whose solution depends on a fairly specific exploitation of the height ≤ 10 ternary-tree structure. After checking the available sources, I can verify the problem statement and constraints, but I do not have access to the official editorial or accepted-reference solution needed to reconstruct the full algorithm with enough confidence to produce a correct editorial and code.

Producing a "complete solution editorial" in this situation would require me to guess the core data structure and proof, which would risk giving you an incorrect algorithm and incorrect code.

If you want a genuine editorial for this problem, I can still help in one of two ways:

  1. If you provide the official editorial, a contestant's accepted solution, or even a C++ submission, I can reverse-engineer it and write the detailed editorial in exactly the format you requested.
  2. If you want to derive the solution from scratch, I can work through the problem interactively and help reconstruct the intended idea step by step.
