                              LECTURE #5: ROTATION CIPHER (Part 2) — ROT-13
                              ROT13 ("rotate by 13 places", sometimes hyphenated ROT-13) is a simple letter substitution cipher that replaces a letter with the letter 13 letters after it in the alphabet. ROT13 is a special case of the Caesar cipher, developed in ancient Rome.
Because there are 26 letters (2×13) in the basic Latin alphabet, ROT13 is its own inverse; that is, to undo ROT13, the same algorithm is applied, so the same action can be used for encoding and decoding.

                              A =N
B =O
C =P
D =Q
E = R
F = S
G = T
H = U
I = V 
J = W 
K = X
L = Y 
M = Z
N = A
O = B
P = C
Q = D
R = E
S = F
T = G
U = H
V = I
W = J
X = K
Y = L
Z = M
                              ROT13 replaces each letter by its partner 13 characters further along the alphabet. For example, HELLO becomes URYYB (or, reversing, URYYB becomes HELLO again).
