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

THE LOGIC FOLLOWED HERE IS :

ADDITION OF REVERSE VALUE OF POSITIONAL ALPHABET

W → REVERSE VALUE → D = 4

A → REVERSE VALUE → Z = 26

V → REVERSE VALUE → E = 5

E → REVERSE VALUE → V = 22

AND

S → REVERSE VALUE → H = 8

O → REVERSE VALUE → L = 12

U → REVERSE VALUE → F = 6

N → REVERSE VALUE → M = 13

D → REVERSE VALUE → W = 23

SIMILARLY

L → REVERSE VALUE → O = 15

I → REVERSE VALUE → R = 18

G → REVERSE VALUE → T = 20

H → REVERSE VALUE → S = 19

T → REVERSE VALUE → G = 7
