A Lagged Fibonacci Sequence

Problem Statement

A sequence is defined as:

  • $g_k = 1$, for $0 \le k \le 1999$
  • $g_k = g_{k-2000} + g_{k - 1999}$, for $k \ge 2000$.

Find $g_k \bmod 20092010$ for $k = 10^{9\times 2^N}$.

Submit Answers

You need to submit in the format: "N:problem(N)", possibly with multiple values at once, separated by commas, with $N$ between $1$ and $100$.
