Huffman Coding

Huffman coding is a lossless data compression algorithm that assigns variable-length codes to symbols in a message or data stream. It was developed by David A. Huffman in 1952 while he was a student at MIT. The algorithm works by building a binary tree of nodes, where each leaf node represents a symbol in the message and each non-leaf node represents the sum of the frequencies of its children. The tree is built using a priority queue, with the symbols sorted by frequency.

Build

Steps:

1. Put all the files in one directory.
2. Open the directory in terminal.
3. Run command make.

$ make

Run

For encode:

$ ./encode [-h] [-i infile] [-o outfile]

• -h: Shows help and usage
• -i infile: Input containing graph (default: stdin)
• -o outfile: Output of computed path (default: stdout)
• -v: Enable verbose printing.

For decode:

$ ./decode [-h] [-i infile] [-o outfile] 

• -h: Shows help and usage
• -i infile: Input containing graph (default: stdin)
• -o outfile: Output of computed path (default: stdout)
• -v: Enable verbose printing.

For cleaning:

$ make clean
