How Huffman Coding Works

Huffman Coding is a greedy algorithm used for lossless data compression. Instead of using a fixed-length code (like standard 8-bit ASCII) for every character, it assigns variable-length codes based on character frequencies:

• High-Frequency Characters: Assigned shorter binary codes (e.g., 2 or 3 bits).
• Low-Frequency Characters: Assigned longer binary codes.

Prefix Rule: No valid code is a prefix of another code. This allows the decoder to continuously parse a stream of bits without needing explicit separators between characters.
