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

THE LOGIC FOLLOWED HERE IS :

INTERCHANGING PLACE VALUE OF IST AND IIND WITH EACH OTHER

INTERCHANGING PLACE VALUE OF IIIRD  AND IVTH WITH EACH OTHER

INTERCHANGING PLACE VALUE OF VTH AND VITH WITH EACH OTHER

U 21 → (INTERCHANGE) → 14

N 14 → (INTERCHANGE) → 21

R 18→ (INTERCHANGE) → 5

E 5→ (INTERCHANGE) → 18

A 1→ (INTERCHANGE) → 12

L 12→ (INTERCHANGE) → 1

AND

R 18 → (INTERCHANGE) → 8

H 8 → (INTERCHANGE) → 18

Y 25→ (INTERCHANGE) → 13

M 13 → (INTERCHANGE) → 25

E 5→ (INTERCHANGE) → 19

S 19 → (INTERCHANGE) → 5

SIMILARLY

A 1 → (INTERCHANGE) → 9

I 9 → (INTERCHANGE) → 1

R 18 → (INTERCHANGE) → 23

W 23 → (INTERCHANGE) → 18

A 1 → (INTERCHANGE) → 25

Y 25 → (INTERCHANGE) → 1
