83 8 Create Your Own Encoding Codehs Answers Exclusive ((hot))

If you write a decoder that assumes every count is a single digit (e.g., assuming index 0 is a number and index 1 is a letter), your program will break whenever a sequence repeats 10 or more times. Utilizing char.isdigit() dynamically as shown in the solution builds a variable-length string buffer ( count_str ) that handles strings like 15B or 100W flawlessly. Empty String Safety

# 自定义编码方案：5-bit 编码表 encoding_table = 'A':'00000', 'B':'00001', 'C':'00010', 'D':'00011', 'E':'00100', 'F':'00101', 'G':'00110', 'H':'00111', 'I':'01000', 'J':'01001', 'K':'01010', 'L':'01011', 'M':'01100', 'N':'01101', 'O':'01110', 'P':'01111', 'Q':'10000', 'R':'10001', 'S':'10010', 'T':'10011', 'U':'10100', 'V':'10101', 'W':'10110', 'X':'10111', 'Y':'11000', 'Z':'11001', ' ':'11010'

Once the table is set, you can "translate" messages. For example, using the 5-bit scheme, the word "CAB" would be encoded by looking up each letter's binary string: = 00010 A = 00000 B = 00001 Result: 000100000000001 Implementation Tips for CodeHS

To successfully pass the 8.3.8 assignment, your encoding scheme must meet specific criteria: If you write a decoder that assumes every

Why choose this? It’s easy to implement and debug, and it uses a uniform 5‑bit length for every character. The trade‑off: it’s not as space‑efficient as variable‑length schemes, but it’s perfectly acceptable for this exercise.

题目明确要求来实现。后续还有挑战环节，要求把编码扩展到：

The exercise on CodeHS requires you to design a custom binary system to represent text. To pass the autograder, your encoding must follow specific rules regarding character coverage and bit efficiency. 1. Identify the Requirements Understanding the Goal of 8

Most students use fixed-length (all characters are 5 bits) for simplicity, which makes decoding easier because you can just split the string every 5 characters.

本文提供的代码和二进制串已经过严格测试，完全符合CodeHS 8.3.8 “Create Your Own Encoding” 的自动判题规则。你可以放心参考，但建议不要直接照抄。，当你遇到困难时再用这里的示例作为对照，这样才能真正把知识变成自己的能力。

If your rules only apply to lowercase letters, a user entering capital letters might bypass your encoder. Use .toLowerCase() (JS) or .lower() (Python) to safely check character types.
