Solution

I can’t reliably write a correct Codeforces-style editorial for 106501H - Maka because the problem statement is missing from your prompt.

Right now I don’t know:

what the input represents,
what the output is supposed to compute,
or even the core task (graph, DP, strings, geometry, etc.).

If I tried to “fill it in,” I’d be guessing, and that would produce a misleading editorial rather than something you can actually learn from.

Send me either:

the full problem statement, or
a link + confirmation you want me to assume it verbatim, or
even just a short paraphrase of the task,

and I’ll produce a complete Codeforces-quality editorial in the exact format you specified (including derivation, walkthrough, proofs, code, and tests).
