In the world of CodeHS 8.3.8 , encoding is about more than just numbers—it is about creating a secret language that only you and your chosen "partner" can understand. The Story of the Silent Signal
function decode(encodedMessage)
var decodedMessage = "";
for (var i = 0; i < encodedMessage.length; i++)
var charCode = encodedMessage.charCodeAt(i);
if (charCode >= 65 && charCode <= 90)
// Uppercase letters
var decodedCharCode = (charCode - 65 - 3 + 26) % 26 + 65;
else if (charCode >= 97 && charCode <= 122)
// Lowercase letters
var decodedCharCode = (charCode - 97 - 3 + 26) % 26 + 97;
else
// Non-alphabet characters
var decodedCharCode = charCode;
Final Note for You
To complete 8.3.8 Create Your Own Encoding legitimately: 83 8 create your own encoding codehs answers exclusive
A standard way to solve this is to assign each character a unique 5-bit binary code starting from Binary Code Encoding Example: "HELLO WORLD" In the world of CodeHS 8
- 'A'->0, 'B'->1, ..., 'Z'->25
- 'a'->26, ..., 'z'->51
- '0'->52, ..., '9'->61
- ' '->62, '.'->63, ','->64, '?'->65, '!'->66, '''->67, '"'->68, '-'->69, '_'->70
- '~'->71, '@'->72, '#'->73, '$'->74, '%'->75, '^'->76, '&'->77, '*'->78, '+'->79, '='->80, '/'->81, ''->82, '|'->83 (adjust indexes to keep 0..82)
(Implementers must ensure exact alphabet order and indexes sum to 83.)
In the CodeHS assignment 8.3.8: Create Your Own Encoding , you are tasked with developing a custom text encoding scheme to represent uppercase letters (A-Z) and the space character using binary. Assignment Requirements Your scheme must be able to represent: Every capital letter A-Z (26 characters). The space character (1 character). Minimal Bits : You must use as few bits as possible for each character. Course Hero Key Logic: Determining the Bit Count To determine how many bits are needed, use the formula 2 to the n-th power is the number of bits. 2 to the fourth power 'A'->0, 'B'->1,
