In the realm of computer science, data is rarely stored or transmitted in its raw form. is the foundational process of converting information into a specific format to ensure secure, efficient, and standardized communication. Whether it’s converting text to binary, compressing images, or encrypting secrets, understanding how to build your own encoding system is a vital skill.
Because the loop stops before the last character to avoid an "Index Out of Bounds" error, you must manually append the final character and its count after the loop ends. Full Code Solution (JavaScript)

: Systematically link individual letters, digits, or spaces to a distinctive binary value.
If you are stuck on the implementation, here is a clean way to structure your code:
# 1. Create the encoding dictionary encoding_map = "a": "!", "b": "@", "c": "#", "d": "$", "e": "%", # ... continue for the rest of the alphabet def encode_message(message): encoded_result = "" for char in message.lower(): if char in encoding_map: # 2. Swap the letter for the symbol encoded_result += encoding_map[char] else: # 3. Keep spaces or punctuation as is encoded_result += char return encoded_result # Get user input text = input("Enter a message to encode: ") print("Encoded message: " + encode_message(text)) Use code with caution.

: The basic code above shifts spaces too ( ord(' ') is 32 , which becomes 35 , or '#' ). If the autograder requires spaces to stay unchanged, add an if statement to check if char == " ": before encoding.
return result.strip() # Remove trailing space
A: Most autograders expect consistency. Converting the input to uppercase before encoding is a simple and effective strategy.
# 3. Process each character for char in message.upper(): # Convert to uppercase for simplicity if char in encoding_map: result += encoding_map[char] + " " # Add a space between each byte else: # Handle spaces or unsupported characters # You could skip them or map them to a special pattern pass
