Correct! You're the second person to find the answer (the first was not on HN).
Now for the extra credit part: What's the connection between this solution and string theory?

> Working on a branch of physics called supersymmetry, Dr. James Gates Jr., discovered what he describes as the presence of what appear to resemble a form of computer code, called error correcting codes, embedded within, or resulting from, the equations of supersymmetry that describe fundamental particles.
(And while asrp's answer is correct, it would have been nice if he had stated what the code is rather than merely citing the fact that it exists.)
Expanding on this, though, you can improve the average result against an arbitrarily-powerful test-writer by first XOR'ing the test answers with a pre-shared value (key); the resulting value is random (even to very powerful test-writers), so e.g. encoding possible answers into the unused values improves your expected result (i.e. data rate.)
Which string theory? The one in physics or the one in computer science?
