# Title: Container With Most Water
# Difficulty: Medium
# Author: Mu Yang <http://muyang.pro>
################################################################################################################################
# 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
