OK, here is another helpmate challenge:
Compose a helpmate in 4 moves with a single solution. In the solution, Black's 4 moves are promotion to rook. As usual, the initial position should be legal and without promoted pieces.

The stipulation means, there are two problems to solve:
1. From the given position, WHITE moves first, black & white cooperate, white's 5th move is mate.
2. From the given position, BLACK moves first, black & white cooperate, white's 5th move is mate.
