Prefix code

A prefix code is a type of code system distinguished by its possession of the prefix property, which requires that there is no whole code word in the system that is a prefix (initial segment) of any other code word in the system. It is trivially true for fixed-length codes, so only a point of consideration for variable-length codes.
