WebHuffman coding is a greedy algorithm, reducing the average access time of codes as much as possible. This method generates variable-length bit sequences called codes in such a way that the most frequently occurring character has the shortest code length. This is an optimal way to minimize the average access time of characters. dance with barney 2013 mp4

WebHuffman Tree. Step 1: For each character of the node, create a leaf node. The leaf node of a character contains the frequency of that character. Step 2: Set all the nodes in sorted order according to their frequency. Step 3: There may exist a condition in which two nodes may have the same frequency.
