+# 11. Container With Most Water
+
+### 2022-02-23
+
+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
+```
+
+
+
+# Solution
+
+```swift
+class Solution {
+    func maxArea(_ height: [Int]) -> Int {
+        guard height.count > 1 else {
+            return 0
+        }
+
+        var left = 0
+        var right = height.count - 1
+        var area = 0
+        while left < right {
+            var h = 0
+            if height[left] < height[right] {
+                h = height[left]
+                left += 1
+            } else {
+                h = height[right]
+                right -= 1
+            }
+            area = max(area, (right - left + 1) * h)
+        }
+        return area
+    }
+}
+```
