"In computer science and information theory, a Huffman code is a particular type of optimal prefix code that is commonly used for lossless data compression. The process of finding or using such a code proceeds by means of Huffman coding, an algorithm developed by David A. Huffman while he was a Sc.D. student at MIT, and published in the 1952 paper 'A Method for the Construction of Minimum-Redundancy Codes'.When constructing a Huffman tree, we need to know the constructed character set and the probability of occurrence of each character. A commonly used character set contains 26 English letters,a pair of mysterious characters gives the frequency of occurrence of each character.The simplest purpose for Huffman codingis to compress the text segments for network transmission.You need to build a Huffman tree based on the frequency of each character occurrence, then output the weighted path length of this Huffman tree.

The simplest purpose for Huffman coding is to compress the text segments for network transmission. You need to build a Huffman tree based on the frequency of each character occurrence, then output the weighted path length(WPL) of this Huffman tree.
