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

THE LOGIC FOLLOWED HERE IS :

STEP 1   LETTERS ARRANGED IN ALPHABETICAL ORDER

STEP 2   REVERSE THE PATTERN

AS

STEP 1   BLISS = BILSS

STEP 2   BILSS = SSLIB

S → (+0) → G

S → (+1) → T

L → (+2) → N

I → (+3) → L

B → (+4) → F

SIMILARLY

STEP 1   STOP = OPST

STEP 2   OPST = TSPO

T → (+0) → T

S → (+1) → T

P → (+2) → R

O → (+3) → R+
