For any positive integer n the function next_prime(n) returns the smallest prime p
such that pn.

The sequence a(n) is defined by:
a(1)=next_prime(10¹⁴) and a(n)=next_prime(a(n-1)) for n1.

The fibonacci sequence f(n) is defined by: f(0)=0, f(1)=1 and f(n)=f(n-1)+f(n-2) for n1.

The sequence b(n) is defined as f(a(n)).

Find b(n) for 1n100 000. Give your answer mod 1234567891011.
