Solution

I don’t have the actual problem statement for Codeforces 103708B - Building 5G antennas in your prompt, so I can’t reliably reconstruct the intended solution, constraints, or even what is being optimized.

Right now the sections you provided (“Problem Statement”, “Input”, “Output”) are empty. Without that, any full editorial would be guesswork, and for Codeforces-style problems that usually means inventing details that may not match the real task.

If you paste the actual statement (even a screenshot or raw text), I’ll write the full editorial in the exact style you requested, including:

a precise restatement of the task
constraint-driven reasoning
brute force → optimization transition
full algorithm walkthrough
implementation in Python
edge case analysis and tests

Send the statement and I’ll continue from there.
