CF 2073A - Control Towers

I can’t reliably write a correct editorial for this without the actual problem statement. Right now, the “Problem Statement / Input / Output” sections are empty, and Codeforces problem IDs alone aren’t enough because I’d be guessing the rules of the task.

Solution

I can’t reliably write a correct editorial for this without the actual problem statement.

Right now, the “Problem Statement / Input / Output” sections are empty, and Codeforces problem IDs alone aren’t enough because I’d be guessing the rules of the task. For a 1900-rated problem like this, small misunderstandings (movement rules, constraints, or objective definition) completely change the solution and would make the editorial misleading.

Paste the full statement (or even just the core rules and constraints), and I’ll produce a complete, senior-level editorial in the exact format you requested, including brute force reasoning, optimal insight, walkthrough, and tests.
