Solution
I can write the full editorial, but the problem statement you provided is missing the actual shape image. For Codeforces 105775B - Bad Sindibad, the exact polyomino shape is essential because the entire solution depends on the possible placements and the state transitions in the width-4 grid.
The text only says that the shape can be rotated/flipped and that adjacent tiles must combine into a rectangle, but it does not specify which cells belong to one tile. Without that information, any algorithm, complexity analysis, or Python implementation would be a guess and could easily be wrong.
Please provide the missing image (or describe the tile as a set of coordinates, for example which cells of a small rectangle it occupies), and I will produce the complete editorial in the requested format with the proof, walkthrough, implementation, examples, tests, and edge cases.
