You are given an integer array ~height~ of length ~n~. There are ~n~ vertical lines drawn such that the two endpoints of the ~i^{th}~ 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:*
#+begin_src
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.
