Use of Huffman coding in information and communication can greatly improve channel efficiency, shorten the time of message transmission and reduce transmission costs. However, this requires the sender through a coded system treats data encoding and decoding in the receiver interprets the data (resiliency). duplex channel (channel can be bi-directional transmission of information), each end needs a complete encoding/decoding system. Try this messaging write a Huffman encoder/decoder. The system can switch between characters with the binary value. Files that can be used in a computer system user, which can save memory, when the user uses and can be converted to a character form. Also implements frequency statistical character of the given file, and the corresponding binary value and the file encoding and decoding. 1 the statistical weights; 2 establish Huffman tree: reading n characters from the structure array and n weights, built by static checking in three three-pointed list of Huffma
