Huffman code using greedy method

WebGreedy algorithms are quite successful in some problems, such as Huffman encoding which is used to compress data, or Dijkstra's algorithm, which is used to find the shortest path through a graph. However, in many problems, a greedy strategy does not produce an optimal solution. Web2 dec. 2013 · Basically there are three methods on a Huffman Tree, construction, encoding, and decoding. The time complexity may vary from each other. We should first notice that (see Wikipedia): . In many cases, time complexity is not very important in the choice of algorithm here, since n here is the number of symbols in the alphabet, which is …
