Alice received the following encrypted message, "10 21 52 26" from bob, who had encrypted it using the rsa cypher with alice's public key (pq, e) = (55, 3). alice knows that her private key is 27. what is bob's message after alice decrypts it? (assume bob encoded one letter at a time using the encoding a = 01, b = 02, c = 03, z = 26.)
