Decoding Messages If we assign numbers to theletters of the alphabet as follows and assign 27 to ablank space, we can convert a message to a numericalsequence. We can “encode” a message by adding 3 toeach number that represents a letter in a message. Thus, the message “Go for it” can be encoded byusing the numbers to represent the letters and furtherencoded by using the function C(x) = x + 3. Thecoded message would be 10 18 30 9 18 21 30 12 23.Find the inverse of the function and use it to decode23 11 8 30 21 8 4 15 30 23 11 12 17 10.
