Solution

I can write the full editorial in that format, but I’m missing the actual problem statement for Codeforces 106487B “Canal con interferencias”.

I could not reliably find the problem details from the ID alone, and inventing the statement, constraints, examples, or algorithm would likely produce a wrong editorial.

Please paste the Problem Statement + Input + Output + Samples (or a link to the problem), and I’ll generate the complete editorial with all requested sections and a correct Python solution.
