This project was a desktop implementation used to examine Huffman compression in terms of both execution cost and the resulting compressed size.

## From Frequencies to Prefix Codes

Huffman coding starts from symbol frequencies and repeatedly combines low-frequency nodes into a binary tree. Paths from the root to leaves define variable-length bit codes.

Frequently occurring symbols can receive shorter codes while less common symbols receive longer ones. Because the code set is prefix-free, the bit stream can be decoded unambiguously without inserting delimiters between symbols.

## Implementation Cost

The mathematical algorithm is only part of application performance. Building the frequency table, selecting low-weight nodes, constructing the tree, packing variable-length bits and performing file I/O all contribute to total execution time.

The surviving project record reports that the compressed output was approximately 58% of the original test-file size.

That figure is not a universal Huffman compression ratio. Compression depends on the symbol distribution of the input; already-compressed or high-entropy data may provide little benefit.

## Algorithmic Context

Huffman coding is a lossless frequency-based prefix-code method. Its wider data-structure and algorithmic context is covered in my [Data Structures and Algorithm Analysis](/en/data-structures-and-algorithm-analysis) notes.

A repeatable benchmark of the same code should report compression ratio, encode/decode time, memory use and the exact test corpus as separate metrics.
