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.
思路：两根线中，短线决定了总面积。所以从左右两边向中间靠拢
代码：
class Solution { public: int maxArea(vector<int> &height) { int max=0; int tempArea=0; int size=height.size(); if(size==0) return 0; int left=0; int right=size-1; while(left<right){ tempArea=min(height[left],height[right])*(right-left); height[left]<=height[right]?++left:--right; if(tempArea>max) max=tempArea; } return max; } };
