In this specific exercise:

Before coding, think about the type of encoding you want to create. Will it be a shift cipher, a substitution cipher with a key, or something more complex? Using a simple sequential mapping, the phrase "HELLO

# Calculate the new shifted index # The modulo operator (%) handles the wrapping from Z back to A new_index = (index + 5) % 26 # Calculate the new shifted index # The

(Enough for 27 characters)Therefore, your encoding must use per character. 3. Build the Encoding Table
