Container With Most Water

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.

Your program should return an integer which corresponds to the maximum area of water that can be contained ( Yes, we know maximum area instead of maximum volume sounds weird. But this is 2D plane we are working with for simplicity ).

Note: You may not slant the container.

Example :

Input : [1, 5, 4, 3]
Output : 6

Explanation : 5 and 3 are distance 2 apart. So size of the base = 2. Height of container = min(5, 3) = 3. 
So total area = 3 * 2 = 6

NOTE: You only need to implement the given function. Do not read input, instead use the arguments to the function. Do not print the output, instead return values as specified. Still have a question? Checkout Sample Codes for more details.
