ans is 1..
put n=1 in f(2n)...then u get f(2)=f(1)=1....similarly put n=2,3....then u get
f(4)=f(6)=f(8)=......=f(24)=1..............(1)
now put n=1 in f(2n+1)=f(n)^2-2..........u get......f(3)=f(1)^2-2= (1-2) = -1
similarly..place n=2,3,...in that...u get f(5)=f(7)=f(9)=.....=f(25) = -1...........
now add them...u get 1
plz approve if ans is correct :)
