Minimum Cost to Make at Least One Valid Path in a Grid
Each cell of grid points to a neighboring cell: 1 means right, 2 left, 3 down, and 4 up. Some arrows may point outside the grid. You may change any cell’s arrow at a cost of 1, changing each cell at most once. Find the minimum cost needed to create a path that starts at (0, 0), follows the arrows inside the grid, and ends at (m - 1, n - 1). The path need not have the fewest steps.
