You are given an integer $$$n \leq 10^9$$$. Your task is to compute the number of ways $$$n$$$ can be expressed as the sum of even numbers. Since the answer could be very large, compute it modulo $$$10^9 + 7$$$.

Sample : $$$n = 8$$$

$$$8 = 6 + 2$$$

$$$8 = 4 + 4$$$

$$$8 = 4 + 2 + 2$$$

$$$8 = 2 + 2 + 2 + 2$$$

Therefore for $$$n = 8$$$ the answer would be $$$4$$$
