Both
|
|
|
None of the above

Explanation:
Detailed explanation-1: -LZ77 and LZ78 are the two lossless data compression algorithms published in papers by Abraham Lempel and Jacob Ziv in 1977 and 1978. They are also known as LZ1 and LZ2 respectively. These two algorithms form the basis for many variations including LZW, LZSS, LZMA and others.
Detailed explanation-2: -For example, LZ77 is a lossless compression file type.
Detailed explanation-3: -The algorithms used in lossless compression are: Run Length Encoding. Lempel-Ziv-Welch (LZW) Huffman Coding.
Detailed explanation-4: -The LZ77 Compression Algorithm is used to analyze input data and determine how to reduce the size of that input data by replacing redundant information with metadata.
