8.3 8 Create Your Own Encoding Codehs Answers |best| Link

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.

1. Introduction: What is 8.3.8?

In the CodeHS curriculum (typically for AP Computer Science Principles or introductory Python), 8.3.8 “Create Your Own Encoding” is a milestone exercise. It asks students to move from being users of encoding (like ASCII or Unicode) to being designers. 8.3 8 create your own encoding codehs answers

result = ""

    result += "27"
  else if ch == ".":
    result += "28"
  else:
    result += format(ord(ch) - ord('A') + 1, width=2, pad='0')
return result

The minimum number of bits required to encode 26 uppercase letters and a space is using 6 bits instead?

9) Notes on choices (brief)

• Two-digit mapping is simple and unambiguous for A–Z and a few punctuation marks.
• ASCII/8-bit and binary are standard and support all characters but produce longer outputs.
• Base-conversion encodings can be more compact but require careful length/header handling.

def encode(message): """Encodes a plaintext message using the custom scheme.""" enc_dict = build_encoding_dict() result_parts = [] for ch in message: if ch in enc_dict: result_parts.append(enc_dict[ch]) else: # If character not in dict, keep as is result_parts.append(ch) # Join with a space to separate tokens for easy decoding return ' '.join(result_parts)

Insight: Works, but no compression – one number per character. Very easy to break if a character isn’t in mapping.
