Amazon Online Assessment (OA) - Maximal Minimum Value Path I
Given a two 2D integer array, find the max score of a path from the upper-left cell to the bottom right cell. The score of a path is the minimum value in that path.
Notice: the path can only right and down.
Examples
Example 1:
Input:
[7,5,3]
[2,0,9]
[4,5,9]
Output: 3
Explanation:
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
In the end, the max score(the min value) of all the paths is 3
.
