Solution

The problem statement section is empty, so there isn’t enough information to write a correct editorial.

For a Codeforces editorial, I need at least the actual task description (what the input grid/graph represents, what counts as an “eight-shaped figure”, and what we are supposed to compute or output). Right now only the title is present, which is not sufficient to reconstruct the logic or constraints.

If you paste the full problem statement, I can produce a complete editorial in the exact format you requested, including the full algorithm, proof sketch, code, and test cases.
