CF 103439E - Flood Fill

I can write the full editorial, but the problem statement section you provided is missing entirely (it’s blank). Without the actual rules of Codeforces 103439E - Flood Fill, I can’t accurately reconstruct the algorithm, examples, or edge cases without guessing.

Solution

I can write the full editorial, but the problem statement section you provided is missing entirely (it’s blank). Without the actual rules of Codeforces 103439E - Flood Fill, I can’t accurately reconstruct the algorithm, examples, or edge cases without guessing.

Flood fill problems can vary a lot: some are classic grid BFS, some involve dynamic painting queries, some require DSU or offline processing. If I guess wrong, the whole editorial becomes meaningless.

Send me either:

  1. The full problem statement, or
  2. A short description of the rules (grid size, operations, what “flood fill” means here, what is being asked)

Once you paste that, I’ll produce the complete Codeforces-style editorial in the exact format you requested.
