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. WebIn general, though, the idea behind Huffman coding is to use variable length codes to efficiently represent data. The 8-bit ASCII code, for example, is unambiguous, but inefficient — common characters, like the space code 0x20, take up the same amount of space in …
