83 8 Create Your Own Encoding Codehs Answers [updated] | AUTHENTIC × SOLUTION |

Don't forget to include an else statement in your loop. If you don't, characters that aren't part of your encoding rules (like spaces or punctuation) will be deleted entirely from the output.

: Utilizing built-in functions to convert letters into numbers.

Applying different encoding rules based on character types (e.g., vowels vs. consonants, uppercase vs. lowercase). 83 8 create your own encoding codehs answers

Every digital cipher relies on a predictable system of rules. Before writing code, you must decide how your algorithm will alter the data. Computer science utilizes several foundational encoding styles. 1. The Shift Cipher (Substitution)

// --- 2. Automatically Build Decoding Table --- const decodeMap = {}; for (const [char, bits] of Object.entries(encodeMap)) decodeMap[bits] = char; Don't forget to include an else statement in your loop

What do you want to use? (e.g., shifting letters, reversing them, changing characters to symbols)

def encode_text(plain_text): encoded_result = [] # Convert text to lowercase to match our map keys plain_text = plain_text.lower() for char in plain_text: if char in ENCODE_MAP: encoded_result.append(ENCODE_MAP[char]) else: # Handle characters not defined in your map (optional fallback) continue return encoded_result Use code with caution. 3. Writing the Decoding Function Applying different encoding rules based on character types

In JavaScript, strings can be analyzed similarly to arrays, or you can leverage native string methods.

return result

Both code examples above follow the same core logic for a complete and functional encoding system.

function start() // 1. Ask the user for the text they want to encode var secretMessage = readLine("Enter a message to encode: "); // 2. Define your custom shift key var shiftValue = 4; // 3. Initialize an empty string to hold the result var encodedMessage = ""; // 4. Loop through every character in the original message for (var i = 0; i < secretMessage.length; i++) // Get the ASCII code of the current character var originalCode = secretMessage.charCodeAt(i); // Apply the custom shift to create a new code var newCode = originalCode + shiftValue; // Convert the new code back into a character var encodedChar = String.fromCharCode(newCode); // Append the encoded character to the final result string encodedMessage += encodedChar; // 5. Print the final encoded string to the console println("Your encoded message is: " + encodedMessage); Use code with caution. Python Solution for CodeHS 8.3.8
