Solution

I cannot responsibly write a correct editorial for “Codeforces 106017J - Sargento Camelas Rico” yet, because the actual problem statement (input/output description and constraints) is not present in the prompt and is not reliably recoverable from the contest context alone.

From the partial metadata we can see only the title and that it is a Gym problem submission, but nothing about what is being computed. Any attempt to “fill in” the statement would risk inventing a different problem entirely, which would make the editorial useless or misleading.

If you paste the full statement (or even just the core task description and constraints), I can immediately produce a complete Codeforces-style editorial in the exact format you requested, including intuition, optimal approach, proofs, implementation, and test cases.

If you want, you can also just send:

input format
output format
constraints
sample tests

and that is enough for me to reconstruct everything cleanly.
