Given an array of positive integers `height` representing heights, find two lines which together with the x-axis forms a container and return the maximum amount of water the container can hold.
height = array of positive integers representing line heights
maximum area of water that can be contained
Example 1:
Input:
height = [1,8,6,2,5,4,8,3,7]
Output:
49
Explanation:
Container between lines at index 1 (height 8) and index 8 (height 7) holds 7 * (8 - 1) = 49.
Example 2:
Input:
height = [1,1]
Output:
1
Explanation:
Only possible container holds 1 * (1 - 0) = 1.
Example 3:
Input:
height = [4,3,2,1,4]
Output:
16
Explanation:
Container between lines at index 0 and 4 holds 4 * (4 - 0) = 16.
