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

THE LOGIC FOLLOWED HERE IS :

GIVEN  LETTERS  IN  A  WORD ARE ARRANGED IN ALPHABETICAL ORDER

THEN FIRST 3 LETTERS AND LAST 3 LETTERS ARE INCREASED OR DECREASED BY +5 AND -5

MIDDLE LETTERS IS THE SAME

AS

PAYMENT = TNEMYAP

T → (+5)  → 6

N → (+5)  → 10

E → (+5)  → 18

M → (SAME)  → 14

Y → (-5)  → 11

A → (-5)  → 15

P → (-5)  → 20

AND

JUSTIFY = YFITSUJ

Y → (+5)  → 11

F → (+5)  → 14

I → (+5)  → 15

T → (SAME)  → 19

S → (-5)  → 15

U → (-5)  → 16

J → (-5)  → 20
