Compressions algorithms Run-length encoding (RLE) Very simple lossless compression algorithm. https://en.wikipedia.org/wiki/Run-length_encoding Lempel–Ziv–Welch (LZW) Simple dictionary lossless compression algorithm. https://en.wikipedia.org/wiki/Lempel%E2%80%93Ziv%E2%80%93Welch Transformations algorithms Burrows–Wheeler transform (BWT) Encoding and decoding strings or lists with own alphabets. Been programmed to avoid wasting too much memory - is not using the rotation string, but use the rotation vectors. https://en.wikipedia.org/wiki/Burrows%E2%80%93Wheeler_transform Move to front (MTF) Encoding string or list of chars to list of integers. Decoding list of integers to string. This transformation algorithm uses full ASCII stack. https://en.wikipedia.org/wiki/Move-to-front_transform Discrete Cosine transform (DCT) Encoding and decoding list of numbers. - only 1D https://en.wikipedia.org/wiki/Discrete_cosine_transform Binary codes and functions Helper functions strBinToInt Binary number representation by string convert to integer. For example: '101' to 5 strOctToInt Octet number representation by string convert to integer. strHexToInt Hexadecimal number representation by string convert to integer. intToBinStr Integer number convert to binary number representation by string. intToOctStr Integer number convert to octet number representation by string. intToHexStr Integer number convert to hexadecimal number representation by string length Length of binary integer number getFirstBits getLastBits getValueInPosition cutFirst cutLast resplitBinaryCodes Binary codes Fibonacci BCD
