Polybius cipher

Encryption Recall that one creates a 5x5 Polybius square by writing down the alphabet row by row, starting with the keyword (with duplicate letters removed) and then followed by the rest of the letters in the alphabet in order. An example with the keyword "DERANGEMENT" can be found in section 1.2.2 of the textbook.

Please do the same: Write down a 5x5 Polybius square using the keyword "VOYAGER". Then use that to encrypt the message "It has been said that astronomy is a humbling and character-building experience."

Decryption Using the square you wrote down above, decrypt this ciphertext: 33 51 32 14 45 23 21 21 42 45 14 33 25 51 32 14 51 14 45 51 22 12 42 12 41 13 33 45 14 32 52 41 23 35 33 42 15 14 42 25 24 32 14 22 14 24 51 21 22 23 52 33 35 25 33 42 15 21 54 43 21 22 33 21 42 24 21.

1. Polybius encryption: the ciphertext based on the message starting with "It has been said...".
2. Polybius decryption: the deciphered ciphertext written as a message, that is, with spaces, capitalization, and punctuation added
