8.3.8 — Create Your Own Encoding (CodeHS): A Practical, Engaging Guide

• Encoding rule: Map letters A–Z → 01–26 (two digits per letter). Use 27 for space, 28 for period, 29 for comma.
• Example: "HELLO"
  • Encoding Function: Takes a string and a shift value as input and returns the encoded string.
  • Decoding Function: Takes an encoded string and the same shift value, returning the original string.

  The CodeHS 8.3.8 Create Your Own Encoding activity requires designing a 5-bit binary representation to map 27 characters, specifically the English alphabet and a space. A valid solution assigns a unique 5-bit code to each letter (e.g., A=00000, B=00001) to meet the minimum bit requirement. For further community discussion and tips, see the conversation on Reddit .
