Run-Length Encoding (RLE): It is a simple lossless compression algorithm that replaces consecutive repeated characters or symbols with a count and the character itself.
Lempel-Ziv-Welch (LZW) Compression: It is a popular lossless compression algorithm used in file formats such as GIF and TIFF, which builds a dictionary of frequently occurring patterns and replaces them with shorter codes.
Burrows-Wheeler Transform (BWT): It is another lossless compression technique that rearranges the characters in a string to improve compressibility by exploiting similarities between adjacent characters.
