Encrypt the message " MATH " by translating the letters into numbers
and then applying the encryption function given, and then translating the numbers back into letters.
(a) f(p) = (7p + 5) mod 26
(b) f(p) = (17p + 11) mod 26
(c) f(p) = (5p + 7) mod 26
%3D
Use A = 0,B = 1,C = 2,D = 3,E = 4,F = 5,G = 6,H = 7,1 = 8, J = 9,K = 10,L = 11,M = 12,N = 13,0 = 14,P = 15,Q = 16,R = 17,
S = 18,T = 19,U = 20,V = 21,W = 22,X = 23,Y = 24,Z = 25
