Using Huffman coding for communication can greatly improve the channel utilization, shorten the transmission time and reduce the transmission cost. However, it is required that the transmitted data be encoded by a coding system at the sending end and decoded by the receiver. For a duplex channel (i.e., a channel capable of two-way transmission of information), each end requires a complete encoding or decoding system. Write a Huffman code system for this information sending station.
