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])`.

Find two lines that together with the x-axis form a container, such that the container contains the most water.

Return the maximum amount of water a container can store.

Notice that you may not slant the container.

Example 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:

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

Constraints:

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