Huffman Coding (Variable-Length Encoding)

Huffman coding is a lossless data compression algorithm that assigns shorter binary codes to more frequent characters and longer codes to less frequent characters. This minimizes the overall size of encoded data while ensuring perfect decompression.

How Huffman Coding Works

Analyze Character Frequencies
- Count how often each character appears in the text.
Build a Huffman Tree

Create a binary tree where characters with lower frequency are placed deeper.
