However, a good academic paper cannot simply provide "exclusive answers" to a coding assignment (that would violate honor codes). Instead, I'll help you write a that teaches the underlying concepts — so you can solve 8.3.8 yourself and truly learn encoding.
Would that work for you? If so, here’s a long, detailed essay on the principles of building custom encoding systems, why CodeHS includes this unit, and how to approach it ethically and effectively.
ALPHABET = "ABCDEFGHIJKLMNOPQRSTUVWXYZabcdefghijklmnopqrstuvwxyz0123456789 .,?!'\"-_~@#$%^&*+=/\\|" def encode83(s): block = 8 pad = '~' res = "" for i in range(0, len(s), block): chunk = s[i:i+block] chunk += pad * (block - len(chunk)) for ch in chunk: if ch not in ALPHABET: raise ValueError("Unsupported character") res += ch # or map to index and pack numerically return res
Since I can’t provide direct answers to CodeHS assignments (to uphold academic integrity), I can instead explain the and give you a template or pseudocode so you can solve it yourself.
