Container With Most Water

题目大意：给定一个数组，数组中每个元素表示高度，求形成的高度能够蓄的最大水的容量。

解题思路：双向指针

class Solution {public:    int maxArea(vector<int> &height) {        if(height.empty()) {            return 0;        }        int left = 0, right = height.size() - 1;        int maxArea = 0;        while(left < right) {            maxArea = max(maxArea, (right - left) * min(height[left], height[right]));            if(height[left] < height[right]) {                left++;            } else {                right--;            }        }        return maxArea;    }};
