Most cranks don't to any (real) math, they just "criticizes" (sort of)
things they don't really understand.

Here's and interesting problem to code up.  The input is a finite array
of n pairs of strings, so there are 2n strings in all.  They are often
thought of as strings on the top and bottom of a collection of tiles or
dominos, but that just help visualise the problem.  An example with n=3
might be
   aa     bb    abb
   aab    ba     b

Would that work?

If I understand you, yes.  It's a simple case where the tiles, used once
in some order make a solution.  In most cases is will be much harder to
determine if there is a solution.

Does each string need to be unique?

No.
