Container With Most Water

题目描述:

Given n non-negative integers a1a2, ..., an, where each represents a point at coordinate (iai). n vertical lines are drawn such that the two endpoints of line i is at (iai) 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.

解题方案:

遍历所有方案,找到最大值。下面是该题的代码:

 1 class Solution { 2 public: 3     int maxArea(vector<int> &height) { 4         int maxAre = 0; 5         int area = 0; 6         int len = height.size(); 7         int left = 0; 8         int right = len -1; 9         while(left < right){10             int high = height[left] > height[right]? height[right]:height[left];11             area = high * (right - left);12             if(area > maxAre){13                 maxAre = area;14             }else if(height[left] > height[right]){15                 right--;16             }else {17                 left++;18             }19             20         }21         return maxAre;22     }23 };
