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

THE LOGIC FOLLOWED HERE IS :

INCREASING ORDER OF POSITIONAL VALUE OF LETTERS AS BELOW

 ORGAN

O = 15

R = 18

G = 7

A = 1

N = 13

GIVEN CODE = 1  7   13  15  18 (INCREASING ORDER)

AND,

FINGER

F = 6

I = 9

N = 14

G = 7

E = 5

R = 18

GIVEN CODE = 5  6   7  9  14  18 (INCREASING ORDER)

SIMILARLY

NECK

N = 14

E = 5

C = 3

K = 11

GIVEN CODE = 3    5   11   14 (INCREASING ORDER)
