THE LOGIC FOLLOWED HERE IS :

EACH LETTER IS ADDED BY 1 AND EVERY TWO LETTER

INTERCHANGE THEIR POSITION IN CODE LANGUAGE

P → (INTERCAHNGE + 1 ) → M

L → (INTERCAHNGE +1 ) → Q

U → (INTERCAHNGE + 1 ) → S

R → (INTERCAHNGE +1 ) → V

A → (INTERCAHNGE+ 1) → M

L → (INTERCAHNGE+ 1) → B

AND

S → (INTERCAHNGE + 1 ) → J

I → (INTERCAHNGE +1 ) → T

N → (INTERCAHNGE + 1 ) → H

G → (INTERCAHNGE +1 ) → O

L → (INTERCAHNGE+ 1) → F

E → (INTERCAHNGE+ 1) → M

THEREFORE

D → (INTERCAHNGE + 1 ) → P

O → (INTERCAHNGE +1 ) → E

U → (INTERCAHNGE + 1 ) → C

B → (INTERCAHNGE +1 ) → V

L → (INTERCAHNGE+ 1) → F

E → (INTERCAHNGE+ 1) → M
