The challenge emphasizes creating a scheme that is both unique and functional, ensuring that any message encoded with your system can be reliably decoded back to its original form.
To build this program cleanly, we will separate the logic into a dedicated function and a main execution block. Step 1: Defining the Function and Vowel Map
my_decoder = {} for key, value in my_encoding.items(): my_decoder[value] = key 83 8 create your own encoding codehs answers
Instead of adding to a character's index or numeric value, a multiplier algorithm multiplies the positioning value by a static key.

This is exactly how UTF-8 works — some characters are 1 byte, some are 4 bytes. The decoder always checks the largest valid byte sequence first.

Before we dive into how to approach this assignment, it's important to understand why it's assigned. The goal isn't to create the "most efficient" or "best" code. The purpose is to help you:
The goal is not just to get a passing grade, but to understand the fundamental concept of (similar to ASCII, UTF-8, or Base64) but on a smaller, custom scale.
