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

THE LOGIC FOLLOWED HERE IS :

VOWELS ARE GETTING SQUARE :

FOR EXAMPLE , E = 5 WILL BE WRITTEN AS 25

CONSONANTS ARE GETTING AN OPPOSITE NUMBER OF ALPHABETS SERIES:

FOR EXAMPLE B = 2 WILL BE WRITTEN AS 25(OPPOSITE)

V = 22 → (CONSONANTS) → 5

A = 1 → (VOWEL) → 1

R = 18 → (CONSONANTS) → 9

I = 9 → (VOWEL) → 81

O = 15→ (VOWEL) → 225

U = 21 → (VOWEL) → 441

S = 19 → (CONSONANTS) → 9

SIMILARLY

P = 16 → (CONSONANTS) → 11

E = 5 → (VOWEL) → 25

N = 14 → (CONSONANTS) →13

S = 19 → (VOWEL) → 8

I = 9 → (VOWEL) → 81

O = 15 → (VOWEL) → 225

N = 14 → (CONSONANTS) → 13
