Stuck need help! The class I'm taking is computer science discrete structures. 

Problem is attached. please view both attachments before answering.

I need help with parts A and B.

Please explain answer so I can fully understand.

Really struggling with this concept. Thank you so much.

Let Set A
{the quick brown fox jumped over the lazy dog} be a set of strings (two or
%3D
more characters) formed by characters (single letters) in the standard alphabet.
Enumerate (assign numbers to) the alphabet as

Consider the following encryption algorithm written in pseudo code:
Encrypt(set):
define f (x) = x + 13 mod 26.
Now,
Vx E characters of A,
If x = 14 mod 26,
> f (x)
Then x →
If not,
Then x → X
