# Huffman Encoding and Decoding
This Python script implements Huffman encoding and decoding algorithms. Huffman encoding is a widely used technique for lossless data compression.
## Usage
1. Make sure you have Python installed on your system.
2. Clone this repository or download the `main.py` file.
3. Open a terminal or command prompt.
4. Navigate to the directory containing the `main.py` file.
5. Run the script using the following command:
```
main.py
```
6. Follow the instructions to enter the name of the file you want to encode.
7. The encoded and decoded files will be saved in the `result` directory.
## Description
The script provides two main functions:
- `encode(input_file, encode_file)`: Encodes the contents of the input file using Huffman encoding and writes the encoded data to the specified output file.
- `decode(encode_file, decode_file)`: Decodes the encoded data from the input file and writes the decoded text to the specified output file.
## File Structure
- `main.py`: The main Python script.
- `result`: Directory to store the encoded and decoded files.
- `README.md`: Documentation explaining how to use the script.
## Requirements
- Python 3.x
- The input file to be encoded
## Example
Suppose you have a text file named `input.txt` that you want to encode:
1. Run the script and enter `input.txt` when prompted.
2. The encoded file (`encode.txt`) and the decoded file (`decode.txt`) will be created in the `result` directory.
