The lack of frequencies didn't bother me - it's easy to add. And yes, I've been thinking for the rest of the day that I should use lazy sequences. In this case the execution time remains O(N²) but as you say the memory footprint becomes more like constant. Definitely a good practice when you can't find a better algorithm.
