Container With Most Water

problem description and solution for the LeetCode problem "Container With Most Water"

LeetCode - The World's Leading Online Programming Learning Platform
You are given an integer array height of length n. There are n vertical lines drawn such that the two endpoints of the ith line are (i, 0) and (i, height[i]).
您将获得一个长度 n 的整数数组 height 。绘制了 n 垂直线，使得 ith 线的两个端点是 (i, 0) 和 (i, height[i]) 。

Find two lines that together with the x-axis form a container, such that the container contains the most water.
找到两条与 x 轴一起形成容器的线，这样容器包含的水最多。

Return the maximum amount of water a container can store.
返回容器可以储存的最大水量。

Notice that you may not slant the container.
请注意，您不能倾斜容器。

Example 1: 示例 1：

Input: height = [1,8,6,2,5,4,8,3,7] Output: 49 Explanation: The above vertical lines are represented by array [1,8,6,2,5,4,8,3,7]. In this case, the max area of water (blue section) the container can contain is 49.

Example 2: 示例 2：

Input: height = [1,1] Output: 1

Constraints: 约束：

n == height.length
2 <= n <= 105
0 <= height[i] <= 104
