UDCode A *code* is a set of strings, called the *code words*. A code is *uniquely decodable* if any string *S* that is a concatenation of code words is so in *exactly one way*. For example, the code "('ab', 'abba', 'b')" is *not* uniquely decodable, because 'abba' . 'b' eq 'ab' . 'b' . 'ab'. But the code "('a', 'ab', 'abb')" *is* uniquely decodable, because there is no such pair of sequences of code words. This module provides a pair of functions to tell whether a set of code words is a uniquely decodable code, and to find an example of sequences of code words whose concatenations are the same, if there is such a pair.
