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. WebA Huffman encoding can be computed by first creating a tree of nodes: Create a leaf node for each symbol and add it to the priority queue. While there is more than one node in the queue: Remove the node of highest priority (lowest probability) twice to get two nodes.
