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

THE LOGIC FOLLOWED HERE IS :

S → (OPPOSITE) → H → 8 × 2 = 16

T → (OPPOSITE)  → G → 7 × 2 = 14

R → (OPPOSITE) → I → 9 × 2 = 18

E → (OPPOSITE) → Y → 25 × 2 = 50

A → (OPPOSITE) → V → 22 × 2 = 44

M → (OPPOSITE) → Z → 26 × 2  = 52

F → (OPPOSITE) → N →  14  × 2  = 28

SIMILARLY

P → (OPPOSITE) → K → 11 × 2 = 22

E → (OPPOSITE)  → V  → 22 × 2 = 44

R → (OPPOSITE) → I → 9 × 2 = 18

I → (OPPOSITE) → R → 18× 2 = 36

O → (OPPOSITE) → L → 12 × 2 = 24

D → (OPPOSITE) → W→ 23 × 2  = 46
