No, the
huffman
algorithm is the most efficient, since it assigns the most frequent characters the smallest sequences. And the algorithm already tells you what data structure you need to do to implement
huffman
coding. I haven't looked at it in awhile but I think its just a binary tree of 0's and 1's.
