Description

huffman_coding.py

This script contains the following functions:

• build_huffman_tree_from_codes: Builds a Huffman tree from a dictionary of Huffman codes.
• build_huffman_tree: Builds a Huffman tree from a given text.
• build_huffman_codes: Builds Huffman codes for each character in the tree.
• compress: Compresses a given text file using Huffman coding.
• decompress: Decompresses a compressed file back to its original form.

Example

Suppose you have a text file named example.txt that you want to compress. You can use this script as follows:

1. Run the script and provide the name of the file (example.txt) when prompted.
2. The script will compress the file and save the compressed version as compressed.txt in the result directory.
3. To decompress the file, run the script again and select the compressed file (compressed.txt) when prompted.
4. The script will decompress the file and save the decompressed version as decompressed.txt in the result directory.
