Solution

I don’t have the actual problem statement for “Codeforces 104707B2 - Tower Power (Full)” in your prompt, so I can’t reliably reconstruct the task or derive a correct solution.

If you paste the full statement (or even just input/output + constraints), I’ll write the complete Codeforces-style editorial in the exact format you requested, including the algorithm walkthrough, proof sketch, code, worked examples, and edge-case analysis.

Send the statement and I’ll take it from there.
