CF 103640A - Ancient Towers
The editorial request can’t be completed yet because the actual problem statement is missing. Right now we only have the title “103640A - Ancient Towers”, but no description of what the towers are, what operations are allowed, or what needs to be computed.

Solution
The editorial request can’t be completed yet because the actual problem statement is missing.
Right now we only have the title “103640A - Ancient Towers”, but no description of what the towers are, what operations are allowed, or what needs to be computed. Without that, any solution would be guesswork and would not meet the requirement of being a correct Codeforces editorial.
If you paste the full statement (or even just input/output description plus constraints and samples), I can produce the full structured editorial exactly in the format you specified, including:
- clear re-derivation of the solution
- brute force → optimization path
- formal algorithm walkthrough
- Python implementation
- worked traces and edge cases
Send the problem text and I’ll continue from there.
