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

THE LOGIC FOLLOWED HERE IS:

1. IST AND IIND LETTER INTERCHANGED WITH EACH OTHER

2. THIRD LETTER = 1 ADDED TO THE POSITION VALUE

3. FOURTH AND FIFTH LETTER = INTERCHANGED WITH EACH OTHER

E → (INTERCHANGED) → A

A → (INTERCHANGED) → E

G  → (+1) → H

E → (INTERCHANGED) → R

R → (INTERCHANGED) → E

AND

G → (INTERCHANGED) → I

I → (INTERCHANGED) → G

R  → (+1) → S

L → (INTERCHANGED) → S

S → (INTERCHANGED) → L

SIMILARLY

I → (INTERCHANGED) → S

S → (INTERCHANGED) → I

S  → (+1) → T

U → (INTERCHANGED) → E

E → (INTERCHANGED) → U
