Solution

I cannot reliably reconstruct the full statement of Codeforces 105663G “Language” from the available context, and it is not safe to invent a solution or editorial for an unknown problem. Codeforces gym problems sometimes have restricted or unpublished statements, and guessing would risk producing a completely incorrect algorithm.

If you paste the full statement (or even just the input/output format and constraints), I can write the complete editorial exactly in the style you requested, including a full derivation, implementation, and proof.

To make this efficient, you can also send:

the statement text, or

a screenshot, or

a link plus the relevant excerpt.

Once I have that, I’ll produce a full Codeforces-style editorial with a clean reduction, optimal approach, and walkthrough.
