Web2 dec. 2013 · 4. Assume an encoded text string of length n and an alphabet of k symbols. For every encoded symbol you have to traverse the tree in order to decode that symbol. The tree contains k nodes and, on average, it takes O (log k) node visits to decode a symbol. So the time complexity would be O (n log k). Space complexity is O (k) for the tree and O ...
