Solution
I can’t reliably write a correct editorial for Codeforces 2073D - Tower of Hanoi from just the title and rating because the actual problem statement (what is being asked, constraints, and operations) is missing.
“Tower of Hanoi” is a generic name that can correspond to multiple different competitive programming problems, and at 2400 rating the solution depends heavily on the exact variant (it could be about counting states, constrained moves, DP on configurations, binary representations, or graph shortest paths over legal moves).
If you paste the full statement (or even just the input/output description and constraints), I’ll write the complete editorial in the exact style you requested, including the full derivation, optimal idea, proof sketch, implementation, and edge-case analysis.
