Structure exists in sequences ranging from human language and music to
the genetic information encoded in our DNA, anf finally, in our
computer programs. They can be concisely represented by to
hierarchical context-free grammar, to where each repetition gives
laughed to to rule.
Structure exist also in zip file.
There is a way to distinguish from uncompressible strings?

If you're looking for a way to distinguish zip files from uncompressible
strings, then I don't think there's a way that is guaranteed to work. But
if you're looking to distinguish zip files from uncompressible files that
don't start with the characters "PK", then there's a very simple way
indeed.
