******************************************************

THE LOGIC FOLLOWED HERE IS :

STEP 1.     CONSONANTS  = OPPOSITE LETTERS

STEP2.       VOWELS  = NEXT LETTERS

STEP 3       A - E - I - O-U

AS

B  → (OPPOSITE)  → Y

A → (VOWELS NEXT LETTERS)  → E

C → (OPPOSITE) → X

K  → (OPPOSITE) → P

AND

M  → (OPPOSITE)  → N

I → (VOWELS NEXT LETTERS)  → O

X  → (OPPOSITE) → C

T  → (OPPOSITE) → G

U  → (VOWELS NEXT LETTERS)  → A

R  → (OPPOSITE)  → I

E → (VOWELS NEXT LETTERS) → I

SIMILARLY

F  → (OPPOSITE)  → U

R →  (OPPOSITE)  → I

O  → (VOWELS NEXT LETTERS)→ U

G  → (OPPOSITE) → T

S  → ((OPPOSITE)   → H
