How is Huffman coding implemented in software?

Can you explain how Huffman coding is implemented in software?

Sure! Huffman coding is implemented using a binary tree. First, you create a frequency table of the characters in the input data.

What comes after creating the frequency table?

Next, you build a priority queue from the frequency table, where the least frequent characters have the highest priority.

How do you construct the Huffman tree from the priority queue?

You repeatedly remove the two nodes with the lowest frequency from the queue, create a new internal node with these two nodes as children, and insert it back into the queue.

And how do you generate the codes for each character?

Once the tree is built, you traverse it to assign binary codes to each character based on the path taken to reach them.
