Compression Tool

Single-file Huffman compressor/decompressor in C++ that supports arbitrary binary-safe inputs (text, PDFs, images, binaries). Handles edge cases (empty files, single-symbol inputs) and stores an efficient frequency-table header. Implements priority-queue and tree structures for fast encode/decode.
