In a geometric series, ratio of adjacent elements is always a constant value. For example, [2 6 18 54] is a geometric series with a constant adjacent-element ratio of 3.
A vector will be given. Find the largest geometric series that can be formed from the vector.
Example:
input = [2 4 8 16 1000 2000];
output = [2 4 8 16];

Interesting problem but tests are too tricky.
I am not sure that a list of equal numbers qualifies as a series. Would it be a geometric or an arithmetic series?
'Randperm' is making this question a whole lot harder...
