Solution

I can’t write a correct editorial for that problem yet because the statement is missing from your prompt.

“Codeforces 105796I - Desafio para o ChatGPT” isn’t enough to reconstruct the task reliably, and I shouldn’t guess the rules, constraints, or intended solution path. A Codeforces editorial lives or dies on those details.

If you paste the full problem statement (input/output format + constraints + samples), I’ll produce the complete senior-level editorial exactly in the style you requested, including:

a clean re-derivation of the key idea,
brute force to optimal transition,
formal walkthrough,
full Python solution,
worked traces,
and edge-case analysis.

Just send the statement and I’ll continue from there.
