Total Accepted: 74897 Total Submissions: 217340 Difficulty: Medium
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.

解题思路：
 采用木桶原理，两边有两块隔板。每次以最短的为桶的高，宽度为两个隔板之间的距离。每次算出面积后取最大者
 ，然后短板向内侧移动，依次下去直到两个隔板相遇。
代码如下：

*/
class Solution {
public:
    int maxArea(vector<int>& height) {

        //从两边向内收缩，利用木桶原理

       int res=0;
       int left=0,right=height.size()-1;
       while(leftif(height[left]else{
               res=max(res,height[right]*(right-left));
               --right;
           }
       }
        return res;
    }
};
