Clear Code Encryption Implementation

# Introduction

In this project, you will learn how to implement a simple encryption and decryption algorithm called "Clear Code Encryption". This encryption method was used in China's early telegraph communication system during the late Qing Dynasty.

## 👀 Preview

# Example 1
numb = 1530; encryption_text = "0383"
# Example 2
numb = 0; encryption_text = "9853"
# Example 3
numb = 12345; encryption_text = None

## 🎯 Tasks

In this project, you will learn:

- How to understand the encryption method and its underlying principles
- How to implement the `plain_code_encryption(numb)` function to perform the encryption
- How to test the encryption function with various inputs
- How to handle user input and call the encryption function

## 🏆 Achievements

After completing this project, you will be able to:

- Explain the "Clear Code Encryption" method and its historical context
- Implement a basic encryption and decryption algorithm using Python
- Test and validate the encryption function with different input scenarios
- Integrate user input and output into the encryption script
