The encoding rule uses modular arithmetic (modulo 26) to handle the end of the alphabet. For example, if the letter is 'Z', shifting by 5 wraps around to 'E'.
It increments a counter as long as the next character matches. 83 8 create your own encoding codehs answers exclusive

The CodeHS 8.3.8 "Create your own Encoding" activity requires developing a 5-bit binary scheme to represent 26 capital letters (A–Z) and a space character efficiently. By using a 5-bit mapping (2^5=32), users can map characters sequentially from 'A' (00000) to space (11010) to meet the minimum bit requirements.

Before writing code, you need an encoding scheme. A highly effective approach for this CodeHS assignment is a modified combined with a visual delimiter, or an offset-multiplier mechanism .
Before diving into the code, it's important to understand why CodeHS includes this assignment. In the real world, character encoding forms the bedrock of digital communication. Every time you send a text message, browse a website, or store a file, encoding systems like ASCII or Unicode are working behind the scenes to translate human‑readable characters into binary data that computers can process.
