Container With Most Water

Given n non-negative integers a1, a2,
..., an, where each represents a point at coordinate (i, ai). n vertical
lines are drawn such that the two endpoints of line i is at (i, ai) and (i,
0). Find two lines, which together with x-axis forms a container, such that the container contains the most water.
Note: You may not slant the container.

这道题目 要注意 不能slant the container， 也就是 是最矮的line 觉得高度。

public class Solution {
public int maxArea(int[] height) {
if (height == null || height.length == 0) {
return 0;
}
int l = height.length;
int i = 0;
int j = l - 1;
int res = 0;
while (i < j) {
res = Math.max(Math.min(height[i],height[j])* (j - i), res);
if (height[i] < height[j]) {
i++;
} else {
j--;
}
}
return res;
}
}
