+# java_container_with_most_water
+
+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.
+
+## Examples
+
+**Example 1:**
+
+![https://s3-lc-upload.s3.amazonaws.com/uploads/2018/07/17/question_11.jpg](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`
+
+## 解析
+
+給定一個非負整數陣列 height
+
+其中每個 height[i] 代表 index i 的格版高度
+
+假設 每兩個 height 之間相隔為單位 1 
+
+往中間注水 假設格版本身很薄 所以不計
+
+則兩個 height 所能裝的水的面積 剛好是由比較小的 height * 兩個 height 的 X軸相查距離 = min(height[i], height[j]) *(j -i) if i < j
+
+
+![](https://i.imgur.com/Uqn879I.png)
+
+
+要求寫一個演算法來計算再給定的 height 中所能注入最多面積是多少
+
+由於每個面積都是由兩個 height 來圍出
+
+所以可以透過 two pointer 然後逐步更新最短的 height 的 point 來找尋下一個更多面積的可能值
+
+直到兩個 height 只差 1 
+
+而再這之間不斷把當下最大的做紀錄
+
+初始化 lp =0, rp = len(height), maxArea = 0
+
+當 lp < rp 做以下運算
+
+   area = min(height[lp], height[rp]) *(rp-lp)
+
+ 如果 area > maxArea,  則更新 更新 maxArea = area
+
+ 如果 height[lp] > height[rp], 更新 rp -= 1 否則更新 lp += 1
+
+![](https://i.imgur.com/0ovM7Ly.png)
+
+## 程式碼
+```java
+public class Solution {
+  public int maxArea(int[] height) {
+    int mArea = 0;
+    int lp = 0, rp = height.length -1;
+    while (lp < rp) {
+      mArea = Math.max(mArea, Math.min(height[lp], height[rp]) * (rp - lp));
+      if (height[lp] > height[rp]) {
+        rp--;
+      } else {
+        lp++;
+      }
+    }
+    return mArea;
+  }
+}
+```
+## 困難點
+
+1. 要看出與面積相關的計算方式
+2. 要看出如何找下一個可能的更大的面積
+
+## Solve Point
+
+- [x]  初始化 rp =0, lp = len(height) - 1, maxArea = 0
+- [x]  當 rp < lp 做以下運算
+- [x]  area = min(height[lp], height[rp]) *(rp-lp)
+- [x]  if area > maxArea 更新 maxArea = area
+- [x]  當 height[lp] > height[rp] 更新 rp -= 1 否則更新 lp += 1
+- [x]  回傳 maxArea
