Solution
The problem statement for Codeforces 105471L - Prism Palace is missing from your prompt, so there isn’t enough information to reconstruct the task, constraints, or required algorithm.
Right now we only have the template and headers, but no description of what the input represents, what needs to be computed, or even the output format. Writing a correct editorial without those details would require guessing the problem, which would very likely be wrong.
If you paste the full problem statement (or even just the core description + constraints + sample I/O), I can produce the complete Codeforces-style editorial exactly in the format you requested, including:
A precise re-derivation of the solution,
A clean optimal algorithm explanation,
Full Python implementation,
Worked traces, edge cases, and complexity analysis.
Send the statement and I’ll continue from there.
