I just submitted my dictionary code to the Big Board. My results weren't horrific (well, I did use more memory than anyone else, lol); but I'm a little disheartened when comparing to the best results. I'm having trouble seeing how it would be possible to have both low times and low memory like the top-ranked results show.
Perhaps there are some hints in the walkthroughs, etc, that I missed? Can anyone give me any tips - or point me to where I should've found some - for speeding up my code or decreasing the memory usage?
