Create a variable (e.g., encodedText = "" ) to store the encrypted characters as you build them.

To earn full points on the CodeHS autograder, your code must use a to iterate through the input string, apply your transformation rules character by character, and print or return the final encoded string.

The great insight of ASCII is that every character is represented with (later extended to 8 bits in Extended ASCII). While this is simple and widely supported, it is not necessarily efficient. The letter Z takes the same number of bits as the letter E , even though E is much more common in English text.

Many students forget to account for spaces. If you shift a space character code, it becomes a symbol (like ! ). Decide if you want to encode spaces or leave them as-is.

: This acts as our custom encoding dictionary. It swaps standard vowels and the letter 's' with "Leet Speak" numbers. To earn full points on the CodeHS autograder,

Specifically for loops to iterate through each character of a string.

# Python Example def decode_custom(binary_string): # 1. Create the reverse lookup table decoding_map = v: k for k, v in encoding_map.items() # 2. Split the binary string into individual codes codes = binary_string.split(" ")

Inside the loop, check if the current character str.charAt(i) matches the next character str.charAt(i + 1) . Increment or Commit: If they match, add 1 to your counter. The letter Z takes the same number of

Example:

Is it a letter, a number, or a space?
