* leetcode 11 Container With Most Water
* <p>
* 给定n个非负整数,a1,a2,...an, 每个数字代表一个坐标(i, ai),在坐标上划n条垂直线,垂直线的两个端点分别是
* (i, 0) 和 (i, ai), 找出其中的两条线,使得它们与x轴构成的容器可以盛最多的水,返回最大面积
*/

/**
* 解法分析:
* 本题是求最大面积,两条线之间的面积为(j-i)*Math.min(ai,aj),即长和高的乘积为容器的面积,从题目中我们可以得知
* 最大的长即为(0,length-1),那么我们可以用两个指针分别指向数组首和尾,此时计算出一个面积,这时的面积受制于ai,aj中较小的一个
* 所以我们移动ai,aj中较小的一个指针,寻找更大的面积
* 时间复杂度O(N)
*
* @param height
* @return
