    leetcode11 盛最多水的容器【中等难度】

    # 11. 盛最多水的容器 (opens new window)

    # 英文题: Container with most water

      ●  难度: 中等

    给你 n 个非负整数 a1,a2,...,a``n,每个数代表坐标中的一个点 (i, ai) 。在坐标内画 n 条垂直线,垂直线 i 的两个端点分别为 (i, ai) 和 (i, 0) 。找出其中的两条线,使得它们与 x 轴共同构成的容器可以容纳最多的水。

    说明: 你不能倾斜容器。

    示例 1:

    img

    输入:[1,8,6,2,5,4,8,3,7]
    输出:49 
    解释:图中垂直线代表输入数组 [1,8,6,2,5,4,8,3,7]。在此情况下,容器能够容纳水(表示为蓝色部分)的最大值为 49。

    示例 4:

    输入:height = [1,2,1]
    输出:2

    提示:

    • n = height.length
    • 2 <= n <= 3 * 104
    • 0 <= height[i] <= 3 * 104

    # 分析:

    使用双指针(左右对撞型),以打擂台的方式更新值。

    面积 area = 首尾高度差x水平index之差 = min(height[left], height[right]) * (right - left)


    # 已AC的C++代码:

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