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

THE LOGIC FOLLOWED HERE IS :

SUM OF THE PLACE VALUE IS GETTING REVERSED

AS

BASEBALL = 2 + 1 + 19 + 5 + 1 + 12 + 12

= 54 OPPOSITE IS  45

AND

FEEDBACK= 6 + 5 +5 + 4 + 2 + 1+ 3 + 11 =37

37 OPPOSITE IS 73

SIMILARLY

PRACTICE = 16 + 18 + 1 + 3 + 20 + 9 + 3 + 5

= 75 OPPOSITE IS  57
