The time complexity for encoding each unique character based on its frequency is O(nlog n). Extracting minimum frequency from the priority queue takes place 2*(n-1) times and its complexity is O(log n). Thus the overall complexity is O(nlog n).

Web15 nov. 2011 · 3. Introduction An effective and widely used Application of Binary Trees and Priority Queues Developed by David.A.Huffman while he was a Ph.d student at MIT and published in the 1952 paper “A Method for the Construction of Minimum Redundancy Codes”. Each code is a binary string that is used for transmission of the corresponding … Arithmetic coding and Huffman coding produce equivalent results — achieving entropy — when every symbol has a probability of the form 1/2 . In other circumstances, arithmetic coding can offer better compression than Huffman coding because — intuitively — its "code words" can have effectively non-integer bit lengths, whereas code words in prefix codes such as Huffman codes can only have an integer number of bits. Therefore, a code word of length k only optimally matc…
