The test set gives a false impression as to Matlab's large number precision. For the case of x = 'antidisestablishmentarianism';
y_correct = [2684347378225474636827426476 13474859120710];
The eps(2684347378225474636827426476) is 5.4976e+11. An input of 'antidisestablishmentarianist' will return y_correct = [2684347378225474636827426478 13474859120710]; However, the ism y_correct would score the ist correct as Matlab cannot distinguish the two huge values. A vector output of the first part is one method to get unique solutions. A second method would require uint64 and having multiple values. I like the pairing of encryption and decryption challenges.
I understand. Thanks for the comment.
