- * You are given a m x n 2D grid initialized with these three possible values.
-
- -1 - A wall or an obstacle.
- 0 - A gate.
- INF - Infinity means an empty room. We use the value 231 - 1 = 2147483647 to represent INF as you may assume that the distance to a gate is less than 2147483647.
- Fill each empty room with the distance to its nearest gate. If it is impossible to reach a gate, it should be filled with INF.
-
- For example, given the 2D grid:
- INF  -1  0  INF
- INF INF INF  -1
- INF  -1 INF  -1
- 0  -1 INF INF
-
- After running your function, the 2D grid should be:
- 3  -1   0   1
- 2   2   1  -1
- 1  -1   2  -1
- 0  -1   3   4
