Given a grid of size (n, m), derive the number of paths if points (i, j) and (k, l) are blocked.
💡 Hint: Break it down into sections and compute step by step.
Create a grid-based scenario illustrating how many paths are available if an entire column of intersections is blocked.
💡 Hint: Use combinatorial principles for disconnected components.
