Documentation

Overview

Example

data := []byte("zhang how, zhang how, zhang how, zhang how,")
compressed := HuffmanCompress(data)
fmt.Printf("performance %.4f\n", float64(len(compressed))/float64(len(data)))
de, _ := HuffmanDecompress(compressed)
fmt.Println(string(de))

Output:

performance 0.7674
zhang how, zhang how, zhang how, zhang how,
