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

THE LOGIC FOLLOWED HERE IS:

1) CONSONANTS IS CODED AS ITS OPPOSITE ALPHABET PLACE VALUE.

2) VOWELS IS CODED AS  +3 ALPHABET PLACE VALUE

B → (OPPOSITE ) → Y → ( PLACE VALUE) → F

I → (+3 ) → L → ( PLACE VALUE) → 12

R → (OPPOSITE ) → I  → ( PLACE VALUE) → 9

T → (OPPOSITE ) → G → ( PLACE VALUE) → 7

H → (OPPOSITE ) → S → ( PLACE VALUE) →19

SIMILARLY

D → (OPPOSITE ) → W → ( PLACE VALUE) → F

E → (+3 ) → H → ( PLACE VALUE) → 12

V → (OPPOSITE ) → E  → ( PLACE VALUE) → 5

I → (+3 ) → L → ( PLACE VALUE) → 9

L → (OPPOSITE ) → O → ( PLACE VALUE) → 15
