Given a two 2D integer array, find the max score of a path from the upper left cell to bottom right cell that doesn't visit any of the cells twice. The score of a path is the minimum value in that path.
For example:
Input:
[7,5,3]
[2,0,9]
[4,5,9]
Here are some paths from [0,0] to [2,2] and the minimum value on each path:
path: 7->2->4->5->9, minimum value on this path: 2
path: 7->2->0->9->9, minimum value on this path: 0
path: 7->2->0->5->9, minimum value on this path: 0
Notice: the path can move all four directions. (not only right and down. ALL FOUR DIRECTIONS)
Here 7->2->0->5->3->9->9 is also a path, and the minimum value on this path is 0.
The path doesn't visit the same cell twice. So 7->2->0->5->3->9->0->5->9 is not a path.
In the end the max score(the min value) of all the paths is 3.
Output: 3
