+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:**
+
+![](https://s3-lc-upload.s3.amazonaws.com/uploads/2018/07/17/question_11.jpg)
+
+    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`
