Huffman coding is a data compression algorithm used to reduce data size and generate optimal, variable-length coding. In fixed-length encoding, all the letters/symbols are represented using an equal number of bits. Here, the first row is fixed-length encoding where all the symbols are represented using an equal number of bits.
