Container With Most Water

Given n non-negative integers a₁, a₂,..., a_n,where each represents a point at coordinate (i, a_i). n vertical lines are drawn such that the two endpoints of line i is at (i, a_i)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.
