algorithm decode(encodings):
    define working as an empty string.
    define symbol_table 0 to 256.
    for each encoding in encodings:
        is encoding is in symbol_table?
            define symbols as encoding.
        else:
            define symbols as concatenation of working and working[0].
        for each symbol in symbols:
            output symbol.
            define aug as concatenation of working and symbol.
            is aug in the symbol_table?
                assign working as aug.
            else:
                add aug to symbol_table with key of code.
                assign working as symbol.
                increment code.
