注意第10，11行，如何更新两个指针。

1 public class Solution {
2     public int maxArea(int[] height) {
3         int i = 0, j = height.length - 1;
4         int volume = Math.min(height[i], height[j]) * (j - i);
5
6         while (i < j) {
7             if (Math.min(height[j], height[i]) * (j - i) > volume) {
8                 volume = Math.min(height[j], height[i]) * (j - i);
9             }
10             if (height[i] < height[j]) i++;
11             else j--;
12         }
13         return volume;
14     }
15 }
