Problem

# 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.
