That took me a lot of time thinking, since, as far as I knew, that was impossible. It turned out that the answer he expected was using Hash Tables. I know that usually it works well and somewhere near O(1) but the worst case is still O(n), and as I was being probably more theorical than needed, it didn't lead me to the correct approach.
