Example: A→1, B→2, C→3, space→0
This paper defines a simple custom encoding scheme called "83-8" designed for educational programming exercises. It describes the encoding rules, provides encoding/decoding algorithms with pseudocode, gives worked examples, explains edge cases and error handling, and includes sample CodeHS-style answers and test cases. 83 8 create your own encoding codehs answers exclusive
: Ensure loop boundaries process the very first index ( 0 ) and the absolute final index ( length - 1 ) of the target string. Example: A→1, B→2, C→3, space→0 This paper defines
The decoder reads the compressed string ( 6W2B4W ), extracts the integer multipliers, and expands the letters back into their original layout: WWWWWWBBWWWW . Architectural Breakdown of the CodeHS Assignment provides encoding/decoding algorithms with pseudocode
