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

THE LOGIC FOLLOWED HERE IS:

LETTERS ARE CODED BY THEIR PLACE VALUE :

U → PLACE VALUE → 21

F → PLACE VALUE → 6

H → PLACE VALUE → 8

C → PLACE VALUE → 3

AND

O → PLACE VALUE → 15

F → PLACE VALUE → 6

E → PLACE VALUE → 5

D → PLACE VALUE → 4

SIMILARLY

O → PLACE VALUE → 15

B → PLACE VALUE → 2

F → PLACE VALUE → 6

C → PLACE VALUE →  3
