给定 n 个非负整数 a1,a2,...,an,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。
输入: [1,8,6,2,5,4,8,3,7] 输出: 49

暴力破解
var maxArea = function (height) { let max = 0 for (let i = 0; i < height.length - 1; i++) { for (let j = 1; j < height.length; j++) { const min = Math.min(height[i], height[j]) const area = min * (j - i) if (area > max) max = area } } return max }
双指针
var maxArea = function (height) { let max = 0 let l = 0 let r = height.length - 1 while (l < r) { if (height[l] < height[r]) { max = Math.max(max, (r - l) * height[l]) l++ } else { max = Math.max(max, (r - l) * height[r]) r-- } } return max }
