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.
分析:该题不考虑中间直线的阻挡
解题:
从最前和最后开始往中间移动
class Solution {
public:
int maxArea(vector<int>& height) {
if(height.size()<=1)
return 0;
int maxWater=0;
int i=0, j=height.size()-1;
while(i<j)
{
int localMax=(j-i)*min(height[i], height[j]);
if(localMax>maxWater)
maxWater=localMax;
if(height[i]<height[j])
i++;
else
j--;
}
return maxWater;
}
};
