Webirrelevant information. This can be done by Huffman coding technique. In computer and information theory, a Huffman code is a particular type of optimal prefix code that is commonly used for lossless data compression. Prefix code means that the code assigned to one character is not a prefix of code assigned to any other character. WebHuffman coding is a more sophisticated technique for constructing variable-length prefix codes. The Huffman coding algorithm takes as input the frequencies that the code words should have, and constructs a prefix code that minimizes the weighted average of the code word lengths. (This is closely related to minimizing the entropy.)
