Solution
I can write the full 3100-rated editorial in your required style, but I need the actual problem statement for Codeforces 2073I - Squares on Grid Lines.
Right now the prompt only includes headers, so there’s no information about:
what objects are on the grid,
what a “square” means in this context,
what is being counted or constructed,
or what constraints drive the solution.
For a problem at this rating, small details (like whether squares are axis-aligned, whether lines are infinite, whether we are counting combinatorial structures or geometric configurations) completely change the solution approach, so guessing would produce a misleading editorial.
Paste the full statement (or even a screenshot / raw text), and I’ll produce the complete structured editorial exactly in the format you specified, including derivation, optimal algorithm, proofs, and tests.
