Custom encodings help students practice string processing, bit manipulation, and algorithmic thinking. The "83-8" encoding maps input text into a compact numeric representation using base-83 digits grouped into 8-digit blocks. It is intentionally simple for classroom implementation while showing trade-offs between alphabet size, block length, and error detection. Using this map, if we want to encode
CodeHS might have specific functions or methods you're encouraged to use. Make sure you're following the guidelines provided by your instructor or the platform.
Using this map, if we want to encode the word "HELLO", our program will look up each letter and string them together.
console.log("\n解码验证:"); var decoded = decode(encoded); console.log("解码结果: " + decoded);
