It is possible to show that the length of the longest codeword is no more than a factor of $\log_\phi(2)\approx 1.44$ larger than $-\log_2 p$ , where $\phi$ is the golden ratio; the worst case example …
WebTo write Huffman Code for any character, traverse the Huffman Tree from root node to the leaf node of that character. Following this rule, the Huffman Code for each character is- a = 111 e = 10 i = 00 o = 11001 u = 1101 s = 01 t = 11000 From here, we can observe- Characters occurring less frequently in the text are assigned the larger code.
