> i have mass of data in 2 array A and B:
> A = 0 1 0 0 1 1 0 0
> B = 0 0 0 1 0 1 1 1
> and i have 3 rules to merge them into 3rd array C:
> if A[i] + B[i] == 0 then C[i]=0
> if A[i] + B[i] == 1 then C[i]=1
> if A[i] + B[i] == 2 then C[i]=2
> it looks easy but with the regular way (loop) with large data 
> it takes days (i test it).
> If any one can advise me what to do i'll be happy.
