if block_type == 0: # Zero-filled block block_size = struct.unpack_from('H', compressed_data)[0] compressed_data = compressed_data[2:] decompressed_data.extend(bytes([0]) * block_size) else: # Non-zero-filled block block = self._decompress_non_zero_block(compressed_data) decompressed_data.extend(block) compressed_data = compressed_data[len(block):]

assert data == decompressed_data The Discipline Zerozip algorithm can be implemented in a variety of programming languages. Here is a sample implementation in Python:

# Compress the data using Discipline Zerozip compressed_data = discipline_zerozip.compress(data) discipline zerozip

import discipline_zerozip

# Decompress the data decompressed_data = discipline_zerozip.decompress(compressed_data) if block_type == 0: # Zero-filled block block_size = struct

# Detect zero-filled blocks if self._is_zero_filled(block): compressed_data.extend(self._compress_zero_block(block)) else: compressed_data.extend(self._compress_non_zero_block(block))

def compress(self, data): compressed_data = bytearray() data): compressed_data = bytearray() import struct
