# [11. Container With Most Water](https://leetcode.com/problems/container-with-most-water/)
|
||||
|
||||
## 题目
|
||||
|
||||
Given n non-negative integers a1, a2, ..., an , where each represents a point at coordinate (i, ai). n vertical lines are drawn such that the two endpoints of line i is at (i, ai) and (i, 0). Find two lines, which together with x-axis forms a container, such that the container contains the most water.
|
||||
|
||||
Note: You may not slant the container and n is at least 2.
|
||||
|
||||

|
||||
|
||||
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 1:
|
||||
|
||||
```c
|
||||
Input: [1,8,6,2,5,4,8,3,7]
|
||||
Output: 49
|
||||
```
|
||||
|
||||
|
||||
## 题目大意
|
||||
|
||||
给出一个非负整数数组 a1,a2,a3,…… an,每个整数标识一个竖立在坐标轴 x 位置的一堵高度为 ai 的墙,选择两堵墙,和 x 轴构成的容器可以容纳最多的水。
|
||||
|
||||
|
||||
这一题也是对撞指针的思路。首尾分别 2 个指针,每次移动以后都分别判断长宽的乘积是否最大。
