Huffman code
Huffman encoding

   <algorithm> A {data compression} technique which varies the
   length of the encoded symbol in proportion to its information
   content, that is the more often a symbol or token is used, the
   shorter the binary string used to represent it in the
   compressed stream.  Huffman codes can be properly decoded
   because they obey the prefix property, which means that no
   code can be a prefix of another code, and so the complete set
   of codes can be represented as a binary tree, known as a
   Huffman tree.  Huffman coding was first described in a seminal
   paper by D.A. Huffman in 1952.
