person( 1 ).toLowerCase() randRange(1,25) applyCaesar(M,SHIFT) 0 25

person(2) is expecting to receive an encrypted message with the name of one of his classmates. He knows the message will be encrypted with a Caesar cipher using a shift of SHIFT. When he returns to his desk, he finds a piece of paper with the following message on it:

Original Alphabet
M

Since the message was encrypted by shifting each letter right by SHIFT, to decrypt it we need to shift each letter left by SHIFT.

If we take the first letter C[0] and shift it left by SHIFT, we get the letter M[0].

If we take the second letter C[1] and shift it left by SHIFT, we get the letter M[1].

Continuing this for each letter, the decrypted message is: “M”
