Consider some prime P in factorization, sequence of powers should not have two consecutive non-zero powers, then you can multiply answers over distinct primes since they are independent. The first part can be done by matrix multiplication. Hint: matrix should have 2x2 size.
Thanks, it helped! Can you provide your code for the problem, it will help :)
It would be better for you to implement own code, this might help: http://www.geeksforgeeks.org/count-number-binary-strings-without-consecutive-1s/, http://codeforces.net/blog/entry/22317
These blogs are what I needed :) Thanks a lot again.
