This repository contains a Python program for encoding and decoding text messages using a custom alphabet generated from the frequency of characters in a given text file. It leverages a priority queue (heap) implementation to efficiently process and transform text messages.

EncoderDecoder_python

This Python program allows you to encode and decode text messages using a custom alphabet generated from the frequency of characters in a given text file. It leverages a priority queue (heap) implementation to efficiently process and transform text messages.

Features

• CharList class to represent characters and their frequencies.
• EncoderDecoder class for encoding and decoding messages.
• Read text content from a specified .txt file to build a custom alphabet.
• Encode a message into a list of indices based on the custom alphabet.
• Decode a list of indices back into a readable message.
• Handles lowercase letters and spaces.

Usage

1. Ensure that a text file containing the source text for building the custom alphabet is available in the repository.

2. Create an instance of the EncoderDecoder class and load the text from the file using the get_text method.

3. Encode a message by calling the encode_message method with a lowercase string.

4. Decode a message by calling the decode_message method with a list of indices.
