For example, with these tiles, the sequence 1, 2, 1, 3 produces

    aa    bb    aa    abb
   aab   ba    aab    b

r[0] = aa
r[1] = bb
r[3] = abb
r[4] = aab
r[5] = ba
r[6] = b
Where:
r[0]  r[1]  r[0]  r[3]
r[4]  r[5]  r[4]  r[6]
Is a legit mapping?

 with top string aabbaaabb = bottom string aabbaaabb.  So for this input,
the program should print "yes".  You don't need to give the sequence
that gives the matching top and bottom strings (though that would be a
neat extra), you just have print yes or no depending on whether such a
sequence of tiles exists or not.
