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.)
