"""You run an e-commerce website and want to record the last N order ids in a log.
Implement a data structure to accomplish this, with the following API:

record(order_id): adds the order_id to the log get_last(i): gets the ith last 
element from the log. i is guaranteed to be smaller than or equal to N. 
You should be as efficient with time and space as possible.
