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:Input: [1,8,6,2,5,4,8,3,7]Output: 49
难度：medium
题目：给定 n 个非负整数 a1, a2, … an, 每个点表示坐标上的点。n 条垂直线连接两点 (i, ai) 和 (i, 0)。找出两条线和X轴形成的容器所能盛的最多水。
注意：容器不能倾斜，n 至少为 2.
思路：从最左到最右向中间夹挤。向中间的移动的条件为哪边高度小哪边向中间移动。
